The “Rechnender Raum / Calculating Space” is a light-weight kinetic sculpture by Ralf Baecker that is constructed from sticks, strings, and fishing weights. The sculpture also functions a fully functional neural network. Really impressive piece and the video at the link below is pretty amazing to see it in action. Also, the piece will be showing at Arbots 2008 this coming Sept, in Dublin, Ireland.
