These are pretty excellent. My friend Liz is the brains behind fractalspin,and besides t-shirts she also makes excellent jewelry out of resistors, capacitors, etc. I bought a capacitor necklace for my wife last christmas and she actually wears it out to fancy social engagements.
Also, Liz is an electronic musician and I believe she writes a lot of her songs by writing code. So suck it, laptop-haters.
