The Enjoy Quantum Mechanics T shirt. This is one of the designs within the “Desktop Wave Machine” series. I’ll tell you, this design has almost everything, quantum mechanics, surfing, satire, dolphins, a bikini babe , a dash of “The Beach Boys”, #2 pencils, and the list goes on. I even threw an Oxford comma in that last sentence, just because. So go ahead and surf the crest of a wave function collapse and remember, reality is all in your mind.
