Made a 3dm file of an optical illusion.
The black base squares at top center are each at 14.25 degrees.
Each black and white pair of squares is to be circular arrayed by different counts.
Starting closest to the center point, the counts are 9, 16, 23, 30, 37, and 44.

Cute.

Took me a minute to realise just what the illusion was.

I'll have to try this one:

WOW! My eyes and brain are at odds! Cool.

I'm getting a migraine :-)

I tried to follow the spiral out then my brain started hurting so I stopped...very cool Brian :)
