So I won't go exploring this too soon. But it was great to see it has an actual name. When I was in college I played with color patterning and got similar effects. I knew I was on the right track when the pattern vibrated and I felt like throwing up. You can get some neat illusions and it's worth experimenting. But you want to be careful.MoStarkeyhttps://www.blogger.com/profile/17750403569164418156noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-47937517082250825312015-09-18T12:51:54.417-04:002015-09-18T12:51:54.417-04:00If any of you still want to try it but are afraid ...If any of you still want to try it but are afraid of your painting career taking a three month nosedive, from what I've read and observed, this illusion seems to be completely dependent on the super-specific stimuli of something lined to the same orientation and relative spacial properties of the original induction images. The after-image will actually dissipate if you look at the affected images turn your head 45 degrees and even reappear if you go the full 90! Although you might get an initial, white square in your vision that goes away fairly quickly, you shouldn't have a color after effect unless you start looking at black and white lined images that closely resemble the red and green ones in terms of line spacing. If you do it for just a minute or two you can get the effect very lightly. It shouldn't affect anything major.<br /><br />I think the above info is what actually makes this illusion so cool. You get to watch your brain interact with a visual cue and adapt to these expectations in real time. It's reminiscent of the Blakemore and Cooper kitten experiment, where they used intense visual conditioning to make kittens actually not able to perceive lines oriented a certain way. There's a great demonstration video of the experiment on Youtube for those interested.Sam Borghttps://www.blogger.com/profile/14943977103624166322noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-88042109766788715172015-09-18T10:25:32.693-04:002015-09-18T10:25:32.693-04:00This comment has been removed by the author.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-22542754932841090202015-09-18T10:24:00.488-04:002015-09-18T10:24:00.488-04:00This comment has been removed by the author.Anonymousnoreply@blogger.com
