I'm All Tippy and Shit...
This was my first time seeing any of the "Optical iLLUSIONS" volumes, but I can easily say that this thing ROCKED! I LOVED all of the 'Negative Images'. They were the BEST! I don't understand how they work though, could you explain in "Optical iLLUSIONS Volume 3"? I can never get enough of tippy illusions that make my head spin. Oh yeah, that one illusion you made up worked for me, I saw the picture in full color when I used the 'Cross Your Eyes' Method. Again, great job.
