it's a musicclip from 10 years ago, more or less...
there was a metallic cube, pugged into the wall for power which step by step, following the music it becomes a dancing robot...
It danced various styles, country, hip hop, rock, funk, and then at the end, making a michael Jackson's turn, it unplugged the power, it became a cube again, and the music stipped.
I can't find it...i don't remember the artist nor the title
