Lots of stuff out there at the moment, but I particularly like these wiimote tins. Useful for all sorts of things, not least DS games (you could stuff probably the entire DS library into one of these things).
Shockingly cheap at $3.50, too.
These rather brilliant Tetris ice cube trays, also via GeekAlerts.. not actually sure if you can buy those or whether they're concept.
.. and next, this fab Summoning Stone paperweight, for WoWers out there. Also a bargain at $12, although sold out. The maker'd probably whip one up on demand, mind. Etsy's good like that.
Gosh I could go on. Okay then, I will. A completely brilliant voidwalker's bracelet ring (gosh I want this, but no shipping to the UK):
.. and a Horde bracelet. Interesting that if you do a search for World of Warcraft on Etsy, most of the stuff there is Horde. FTH!
