Well i bought this poster last year, maybe youve seen it
its 5'x3' and you can just sit and stare at it for hours because it spins when you change focus
me being quite interested in graphics i tried to figure out how they did it, so i came up with my own
(after a great deal of trial and error)
basically made this shape
and made a circular pattern copied and shrunk into the middle (repeating over and over)
and came up with this
then took those and made this to sell as one of my posters
there has to be other ways to do this, and just wanted to show you guys, and maybe see
what you might come up with.
