I was very fascinated to see the oldest paintings that we know of in (a whole bunch of) documentary (documentaries, one by the director maniac Werner Herzog) about the Chauvet cave, a reconstruction of which has just opened. Here is a short impression:
Someone seems to share my fascination – I love this game about staring at a cave wall.
I also enjoyed watching the short animation movies which have been produced for the occasion of the opening. You can find them on ARTE.
