After all, Spillman got the idea from a Japanese artist named Ouchi in the first place.<br /><br />Steve, I've heard that there are such things as visual calisthenics to strengthen eye muscles, but I don't know how well that works.James Gurneyhttps://www.blogger.com/profile/01870848001990898499noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-68520634368535471842017-02-06T01:16:16.320-05:002017-02-06T01:16:16.320-05:00I *REALLY* dislike the effect.

I have noticed that when I watch some repetitive circular motion, such as whisking something on the stove, and then look away that the background keeps circling for a couple seconds. That might be a completely different phenomenon though.<br />I'm going to show this to my 30 something daughter later today and see how prominent it is for her.<br />Ernest, I'm pretty sure the illusions rely on very precise alignment of very precise shapes, but I think you could do some pretty interesting experiments with value and hue changes using some graphic design software.
