Hexaflexagon Your Way to Romance
I picked this up at IO9:
I haven’t finished the math yet, but I’m pretty sure if we were to create a large enough hexaflexagon, we would essential create the Stargate.
Okay, so maybe it won’t create the Stargate, but whip this out at the bar and you’re sure to get laid.
Well, maybe not laid, but it’s a lot less illegal than what you normally whip out at the bar.
