Self-Similarity in Fractals

Fractals is a branch of mathematics that artists intuitively grasp because it appeals strongly to the pattern recognition part of the right brain. One of the principles of fractals is the concept of self-similarity. Many forms in nature repeat a certain structure or geometry at various levels of scale.

For example, this ginger root has bulbous branches that leave the main stem, and they tend to do the same thing as the branches get smaller, until the pattern degenerates at the smallest scale.

Romanesco broccoli demonstrates the principle of self-similarity even better. Each spiraling cone is composed of smaller spiraling cones. (Click to enlarge).

In many ferns, the shape of the leaflet resembles the frond. Since this comes down to math, computers can easily invent self-similarity, and this component has given realism to CGI renderings of rocks, plants, clouds, and water, where the phenomenon appears everywhere. Check out the digital fern below, which "grows" as you scroll down.

Woodstock 5: Putting It All Together

For the final day of the creature design workshop, we took our studies, sketches, maquettes and photos and put them together into the final paintings, which we started and discussed. It was fun working together in the beautiful north-lit studio spaces of the Woodstock School of Art.

Having all seen real goats and goat skulls up close, we all have an affection for satyrs. Heinrich Kley (above) was one of many artists we looked at through the course of the week.

At the end, we didn't quite have a full-on bacchanale, but we had a nice pizza party before everyone had to drive home. Thanks to Billy (foreground), Maureen Rogers, Mike Marrocco, Christina Neno, Lester Yocum, Shawn Fields, David Troncoso, Eric Millen, and Jeanette and thanks to the WSA for letting us make the studios our home for the week. And for those who missed this one, maybe I'll see you at another workshop in the future.

Woodstock 4: Maquettes

The creature design class at Woodstock School of Art continued with Day 4 today. Eric Millen bulked up the muscles of his SuperPan.

Eric and Mike loaned the oven in the on-campus barn lodging to cure the Sculpey maquettes.

Lester Yocum decapitated "Fluffy," a stuffed animal he bought last night to use its fake fur. He's actually a really nice guy.

That beige fur was perfect for Lester's lady, a female Pan character with a red glitter dress and plenty of attitude.

Mike Marrocco decided to do a self portrait with Flynn's horns.

Maureen Rogers laid in watercolor washes on her Pan.

All of these maquettes will guide the final painting, which we'll at least start tomorrow.

Woodstock 3: Goat Day

This morning, Billy the goat from Southlands Foundation Farm climbed into Trusty Rusty and rode with us to the Woodstock School of Art where he served as the star model for the goat half of our Pan characters.

Clockwise from lower left: Billy enjoys the attention from David and Eric, Billy checked out Shawn Field's computer, Eric Millen built up his Sculpey Pan figure maquette, and Shawn and Michael Marrocco worked out their character concepts.

Christina Neno showed the relaxed style of maquette building, while David Troncoso sculpted away with Flynn nearby for reference.

Left to right: Lester Yocum came up with an awesome matronly female Pan character, which he sketched on a board and sculpted in 3-D; As David worked, Jeanette (in background) watched Billy, who stayed on his tarp indoors because it was pouring rain outside; Michael gets the Hero's Badge for doing the end-of-day cleanup.

Thanks, Lenny, for letting us borrow Billy!

Woodstock 2: Characterization


If you think yesterday was scary, today was even worse! Those are taxidermy goat eyes, and horns made by Lester.

Yesterday we looked at the comparative anatomy of sheep, goats, deer and humans.

Today we brought in the model, who was directed in a half hour pose by each of the students based on their thumbnail sketches.

We set up Flynn on the C-stand in the exact angle of the model's head, so that you could see the the correct angle and lighting on the horns.

That allowed us to explore how to morph the human and sheep/goat together into a satyr.

It was fun, but challenging for all of us, because it's a different way of seeing than you usually do in art school. We were trying to observe closely, but always be guided by the imaginative ideas we started with in the beginning.

Thanks, Eric!...and forgive me for showing only my own work! Jeanette and I just didn't get photos of the student work. We'll try to remedy that next time. Tomorrow: Goat Day.

Woodstock 1: Sheep Skulls

The first day at the Woodstock School of Art's creature design class was great fun. We had a congenial and talented group of people who came from as far away as Michigan!

The Woodstock school itself has a great tradition leading back to the 1930s, when it was a summer school for Art Student's League instructors, so I was thrilled to be there.

We started off looking at the history of how Pans and satyrs have been portrayed from Greek and Roman days all the way to modern movies and video games. We had a snack of goat cheese and crackers to get us in the mood (thanks, Jeanette!)

Then I brought in five skulls of deer and rams, so we could really study out the anatomy and the variety of horns. I'm holding Flynn, a ram I used to sketch from life years ago when he lived on the farm of a good friend.


We all did thumbnail sketches of a variety of character and compositional ideas, and then tried to "flesh them out" with studies from life.


One of the things I tried to do was to morph the ram's skull with a human skull to see what it looks like. Hmmm...a little scary...got to work on that.

Pan and Satyrs

Today we start our week-long workshop on creature design at the Woodstock School of Art.

We’re going to create the most famous satyr, Pan, based on studies of a human and goat model, some skulls, and other props.

Here’s some background info about the creature we’ll be trying to bring to life:

In Greek mythology, Pan is the protector of flocks and shepherds. He lives in Arcadia, the region of rustic mountain folk. He is a satyr (in Greek, Σάτυροι — Sátyroi), half-human, half goat or ram. (“Satyresses” were a late invention of poets). In mythology they are often associated with male sex drive and vase-painters often portrayed them with uncontrollable erections. The early Greek respesentations of satyrs often showed them as balding and bearded, with human legs and a horse’s tail.

Their chief was called Silenus, a minor deity associated (like Hermes and Priapus) with fertility. These characters can be found in the only remaining satyr plays: Cyclops by Euripedes and Sophocles‘ The Searching Satyrs. The satyr play was a lighthearted follow-up attached to the end of each trilogy of tragedies in Athenian festivals honoring Dionysus. These plays would take a comic approach to the heavier subject matter of the tragedies in the series, featuring heroes speaking in tragic iambic verse and taking their situation seriously as “straight men” to the flippant, irreverent and obscene remarks and antics of the satyrs. The groundbreaking tragic playwright Aeschylus is said to have been especially loved for his satyr plays, but none of them survived.

Satyrs acquired their goat-like aspect through later conflation with the Roman Faunus, a carefree nature spirit of similar temperament. Hence satyrs are most commonly described as having the upper half of a man and the lower half of a goat. They are also described as possessing a long, thick tail, either that of a goat or a horse. Mature satyrs are often depicted with goat’s horns, while juveniles are often shown with bony nubs on their foreheads. Attic painted vases depict mature satyrs as being strongly built with flat noses, large pointed ears, long curly hair, and full beards, with wreaths of vine or ivy circling their balding heads. Satyrs often carry the thyrsus: the rod of Dionysus tipped with a pine cone.

Satyrs are described as roguish but faint-hearted folk — subversive and dangerous, yet shy and cowardly. As Dionysiac creatures they are lovers of wine, women and boys, and are ready for every physical pleasure. They roam to the music of pipes (auloi), cymbals, castanets, and bagpipes, and love to dance with the nymphs (with whom they are obsessed, and whom they often pursue), and have a special form of dance called sikinnis. Because of their love of wine, they are often represented holding winecups, and appear often in the decorations on winecups.

Some satyrs are depicted as old. On painted vases and other Greek art, satyrs are represented in the three stages of a man’s life: mature satyrs are bearded, and are shown as fat and balding, both a humiliating and unbecoming disfigurement in Greek culture.

New Poortvliet Museum


Goed nieuws voor fans van Rien Poortvliet. After the previous museum of Dutch illustrator Rien Poortvliet was forced to close, a new one has opened.

There's a video with a walk-through of the new space at this link.
Thanks, CeGeBe, Nathalie and Erik

Waterfall City Gliders


One of the first paintings that led to Dinotopia was Waterfall City which I painted in 1988. At the time I hadn't thought of dinosaurs or pterosaurs yet. When I imagined how people should cross the gorge to the city, I imagined them flying hang gliders. These sketches show how the designs for those gliders evolved.

Egyptian Mummy Portraits

Long before realistic portrait painting developed in Europe in the Renaissance, Roman-Egyptian artists did striking likenesses in wax on limewood. These Fayum funeral portraits date from around 100 years A.D. According to the Metropolitan Museum:

The finely executed portrait depicts a youth with large, deep-set eyes and a down-turned mouth. His downy moustache indicates that he is no older than his early twenties. A number of mummy portraits represent youths with their first facial hair, a feature that had particular connotations in the Greek-educated society of Roman Egypt. The incipient moustache was both an indicator of the young man's entrance into important social groups and a signal that he was at the prime of sexual attractiveness and vigor.
