Last night, as part of my review of the AverMedia Live Gamer Portable, I streamed random Steam games from my PC for nearly an hour and a half. I took requests. I chatted with readers in the Twitch.tv chat box. I hid in a tunnel and amused myself.

About two years ago, a guy posted a how-to for turning old NES cartridges into a harmonica. If you lack the tools, know-how, or NES carts to make one yourself, someone's now selling them, for $24.99.
