Some old school and newmschool from Christian Moeller

I found Christian Moeller on this webpage vvork. It is a very interesting webpage for art in general.
Oldschool but Coolschool would be for me the Light Blaster: Immaterial Membrane. (faster youtube version) It's only from the 90ties, should be 80ies. It's probably Arduino free.

Newer is do not touch (youtube version).A little gimmicky but funny. As well as Nosy.
