Robert from RobotsRule sends in this video of a RoboBoa, the dancing robot snake. In addition to its disco moves, the RoboBoa has some use doubling as an alarm clock.
By far the most useful feature though is its room sentry function. Using motion tracking it can identify intruders and dance them into submission.
Quite intimidating.
