Sure it's ok to just say phosphenes....but where's the fun in that! Isn't it neat that everyone has slightly different ones?
To share my phosphenes, there are a few....yellow/gray haze, black with purple stars, red checkerboard rotation..
But the best, and the one that always fascinated me as a kid, was the grey/yellow...god...undulating? rotating rectangles? They almost look like prism tessellations..but on top of them, there are these black line images which cycle too quickly for my eye to catch them. I always wanted to be able to draw whatever they were, but they couldn't. Apparently the shapes are fairly constant if you can catch them, and there are papers hypothesizing that primitive cave drawings are these shapes...http://www.iol.ie/%7Egeniet/eng/hedge.htm
It's not called the prisoner's cinema for nothing.
Thanks for all the input everyone!
