It’s the holidays. You have a lot on your mind. You need something to relaaaaaxx. Well, here at Shambollocks! we urge you to turn off your mind, relax, and float down stream with some old and new op art. Add substances as you see fit.

I'd hate to be driving a bus right now!

Plasticene porters with loooking glass ties...

Move your head back and forth while your eyes play...that's right!

Relaxed now? Want to know the science behind this? Sure you do. Head over to Scientific American and find out.
