Post some funny/trippy Music Videos (with a couple to start)

I have seen two pretty trippy music videos

This one is pretty good it has like balls that hit pipes and stuff and make music actually for a moment you actually get trapped into this thing.

This is another one that is pretty wild made by some japenese animator or something it gets pretty wild towards the end.

If you go to Atom films they have some pretty crazy video's here and there they even have the Of Montreal video that is the first time I saw it and it was pretty wild. I mean when do you see a flying acorn?
