LunaTik

From a Chi-based designer who used to run the watch-making show for Nike, LunaTik's bands can convert your iPod Nano into a touchscreen watch on either a semi-permanent basis (via a case made of aerospace-grade aluminum, stainless steel bolts, and high-grade silicone rubber) or a more temporary one thanks to a snap-in-and-out ski-binding-esque design called the Tik Tok, which hopefully doesn't obnoxiously brag about brushing its teeth with a bottle of Jack. And get all fat.
