LEGO Rubik's Cube Confuses

I usually really like LEGO ads, but this one I just don't understand. Why are they showing a Rubik's Cube made out of LEGOs? LEGOs don't rotate like the cube does, so why would someone want to build one? And Rubik's Cubes aren't as fun as LEGOs, they are just kinda frustrating. Does anyone have any insight into this ad for me?
