And you thought that Lego castle you built as a kid was impressive. Two engineers in England have set the world record for completing a Rubiks Cube with a robot made from the ubiquitous plastic blocks. The (somewhat) cleverly-named Cubestormer 3 robot accomplished the impressive feat in just 3.253 seconds — about 62 percent faster than the previous world record, which was held by the second-generation version of the robot. Of course, it takes a bit more than some Lego bricks to come up with that kind of time.
