TIL about the SparkFun SerIO board. This now-discontinued product is an even-simpler-than-Arduino physical computing device. When connected to a USB port, it appears as a serial device. Send it simple commands at 57600 bps and it will read/write pins for you. For example, this configures Pin 13 as an output, and sets the value high:

> C,13,1
Pin: 13 Input/Output: 1
> W,13,1
Pin: 13 Value: 1

This lights the 'Stat' LED

The SerIO is an Arduino Pro 328 - 3.3V/8MHz with a USB serial port on a custom PCB. The code is open source, so you could make one if you really wanted to. The manual, source code (old Arduino pde, but it compiles still) and schematic are in the Documents tab here:
