Katharina,
Go to youtube and search for "Pink and the brain theme". It's great! It's absolutely worth the 3 minutes it will take you to find and listen to it.
There's something to be said for watching nonsense with colors that move around. Cartoons are a nice diversion when you have a tendency to think all the time!
One Thanksgiving evening we were all stuffed to the gills and had a little wine in us, and the show wa on. The characters had discovered that pulling off their outlines made them collapse into puddles of color.
We proceeded to have a deep conversation on perception, Phenomenology, and The Cogito...all inspired by the cartoon.
