Make a Twitter controlled Dalek! via instructables
This is a Dalek robot that can be controlled though Twitter. I mostly made it from stuff that I had lying around, so any of the materials can be easily replaced with what is available. Some things to keep in mind, if you are planning on making anything Twitter controlled is there can be a delay of several seconds between sending a message and the device responding, so it is not ideal for real time control. You can see this to some degree in the video above.
