WARNING: If you wear this shirt, people WILL stare at your chest.
At first glance, it's abstract art. Step back, and a familiar face emerges: Albert Einstein, constructed from exactly 100 circles, exploiting how your visual cortex groups shapes at a distance.
It's not just a shirt. It's a lesson in perception. Because science isn't about being right—it's about being willing to see things differently.
Note: This shirt has the design facing the right side up. I've found that people still sometimes have a hard time recognizing what it is, but when it clicks, it clicks. If you really want to confuse people and laugh as they try to contort their heads to view it upside down, check out the Hard Mode Design. (There's also an easter egg, if you can spot it!)
As a nerd, I love wearing things that declare my nerddom, but in a way that makes other people work for it.
This is a FIRST EDITION version–only 1,000 will be sold with the 1st ed hydrogen mark, and in the future I may do something special for anyone who has one :)
