Spiral of circles optical illusion

I found this illusion and for some reason thought it'd make an interesting print. I guess you can use it as a coaster.

This works fairly well, but you have to print it with 3 contrasting colors. When I used too dark of a grey it didn't work.

I slowed down external perimeters to 10mm/s as a precaution. Still seems to print very fast.
