Okay, so you have to check out this mug—one of the coolest out there (see the 1 min. 49 sec. embedded video below). Yes, I’m a bit biased since I’m the one offering it on the Interval Magic CafePress Store. However, I make next to nothing on these since I’m only the designer and not the actual manufacturer or distributor.
Long story longer, people like me who know a thing or two about graphic-design programs such as Adobe Photoshop or Illustrator can make original custom designs and upload them to websites such as CafePress or Zazzle, which distribute customized T-shirts, mugs, clocks, mouse pads, and more.
Anyway, my Houdini two-face optical illusion is now available on the very magical color-changing mug featured in the following video. Enjoy! (And while you’re at it, feel free to buy a mug to support creative artists like me. Wink.)
