@PvN@sonomu.club I happened on this idea, because I was working for an artist, when I studied computer sciences. He constructed big, transforming sculptures moved by electric motors. He was always out of money, so he contacted IBM, because he thought his art could be interesting to them. And indeed, they sponsored him, all he had to do in return was put up signs in front of his sculptures "Sponsored by IBM". That was quite some time ago, though.
