I can definitely see how that'd work with Dali. I have a few of his prints tacked up on the wall right across from me, and the resemblance is striking...

I haven't seen The Unbearable Lightness of Being, but I think I know the concept. The idea that the universe repeats itself, right? It's very much a comforting idea. The only problem is that even quantum immortality really has to end sometime, considering the natural lifespans of human beings. (Unless you find a universe in which humans are, in fact, immortal.)
