Android IOIO Board

This is a really neat little board available from SparkFun.  It allows you to interface an android phone to an array of microcontroller-like outputs and inputs (PWN, SPI, ADC, etc).  The project has many ready-made Android code examples to get you running and I’m thinking about trying this out!  The page linked shows some projects that others have done, and it’s easy to start thinking about all the cool things you could do with this (especially on a dual core Android like mine!)
