Martin_H from the Parallax forum has built a cool little robot called Drawbot, it uses a Parallax Propeller Microcontroller programmed using PropForth. The main drive for this robot are the cheap $5 stepper motors that are available on eBay out of China. Looks like it is just powerful enough for this project. There is some loss of position after it draws a lot due to things like wheel slip.
 If you are thinking about building a Hexapod you should have a look at the HexPi project. This Hexapod is based around an off the shelf chassis but there are some big plans for the brains, it will be powered by a Raspberry Pi so there will be no limit to the computation power on this tiny walking robot! It is looking good so far, the end result
This Network Time Protocol Clock with Vacuum Fluorescent Display was built by pyrofer for his entry in the Hack a Day Contest. It is still a work in progress with many upgrades still in the works. The project uses a Spark Core which is an Arduino compatible board with built in WiFi. The clock uses the wireless internet connection to request time updates so you will never need to
