We're got 3 mining-related shirts over at SquareWear.biz
now. We offer international shipping and do business exclusively in Bitcoin. Let us know what you think.
Do you have anything a little more... refined?
I'm 26 years old, and most of my t-shirts are one color: white.
I like the idea but I wouldn't be caught dead wearing something that makes me look like teenager/hipster/whatever you call that style ;P
Just a simple "I HEART BTC" or something (like the NYC shirts) or "I MINE COINS" or something like that would probably be simpler to create and would jive with me more.
