Darth Vader leads his minions in a little soft-shoe to the tune of the
Imperial March. This toy from Japan is called the Star Wars Space Opera
“Pop’n Step” Toys. At the touch of a button, you can put the stresses of
the real world aside and watch the villains from a galaxy far, far away
dance while you laugh. There are other characters and configurations available. They apparently sync up when you snap them together.
I wanted these for about five minutes, then I realized it was much easier to just watch them on YouTube. (via Geeks Are Sexy)
