Blockhead Pix

Just dropped from an independent Boulder designer who used to game on a sweet ColecoVision w/ an Atari 2600 adapter, this "8-bit style profile image drawing" iPhone app allows you to design your own old-school video game-like character (or use one of their templates) before one-click uploading them to Twitter -- though in 140 characters, you'd barely be able to give adequate praise to Single Dragon.
