I'm fascinated when people are able to rethink old ideas and come up with something completely new. The Node electrical outlet was designed to address the issue of not enough wall sockets. It's unique design allows you to plug in multiple two pronged cords. While I'm not sure that it is really any more practical than your traditional electrical outlet (it may be less practical really, no three prongs here) you can't deny it looks better.
If anyone finds out if these are available stateside, let us know.
