Yes, it's another toy commercial! I can't get enough, and really -- who doesn't love toy commercials?
Each Cube World has a motion sensor and buttons that let you play with the stick person living in the cube. The really cool feature is that you can connect cubes and let the stick people interact with each other. Apparently, they can cross the Cube World boundaries by their own volition. Could have been a nice setup for teaching kids a wholesome message of world peace, if it weren't for the constant fighting (as featured in the commercial). I know I'm not kidding anyone, of course fighting is fun!
I bet that if you connect enough of these together, they'll develop a hive mind and start disobeying you and ultimately take over the world. Well, one can only hope.
