the things rolling like they are rolling downhill could just be done by having it downhill but doing the room/wall up to hide it or other general tv tricks - it's been 'tidied up' for the advert.
The artist guy really does do these things though - some take hours to complete their cycle.

It's a piece of piss
to fake it - it's just that there are a couple of places where the momentum should have stopped it.
I assumed the entire thing was faked - respect to the artist if (s)he does this for real...
