Gamers know that when your red heart gauge reaches zero you die - something that the "8-Bit Dynamic Life Shirt" illustrates all too well.

These tees come in twos - during normal activities two and a half pixelated hearts will light up but get within hugging distance of the significant other wearing the matching shirt and suddenly the hearts on both of the tees light up until you're fully powered up.

Aaaah ... who said geeks couldn't be romantic?
