Outspoken Genii forum member Brad Henderson has this fascinating public video calling card. Brad reveals, via an "Explaination," the optical illusion behind his business card.
I find this curious as Brad apparently does not like it when others share interesting magical effects with the intent of driving interest in the art. I guess it is ok when it helps you book a gig?
If you are in the Austin area, we encourage you to see Brad perform! If his routine is half as passionate as his trolling, you are in for a great time!
