I first got into bitcoin through reddit a few weeks ago, and bought a little on coinbase to play around with.  Now I like to mess around with alt-coin exchanges (mainly BTC/DOGE on Cryptsy), and I've even made a handy desktop tool for easy DOGE trading using the Cryptsy API:

Someday I'll develop this more and release it as an open source project for others to use.  I'm also really into fine woodworking (and some metalworking) as a hobby, and I'm considering selling some things for BTC or other altcoins.  Here are some things I've made that might be sellable:

Anyhow, messing with cryptocurrency has been pretty interesting so far.  I'm currently mining "quick quick coins" for some reason... maybe just to see if I can .
