Ben Heck, modder extraordinaire, went and created a Portal t-shirt. I assume for Halloween, but possibly just for fun. It's almost identical to this guy's "hole through the chest" shirt, except that one doesn't have a Portal theme, making it forgettable at best. What was I just talking about? Exactly.
Hit the jump for an entirely-too-long 17-minute video of the shirt from conceptualization to building to finished product.

Thanks to Jodie, who will make you your own Portal shirt for just the cost of a cannonball.
