I made three simple computers in glass. There is no breadboard, the connected sculptures with copperwires inside and electrical components soldered to them makes the circuit. I have programmed them for interaction, for connecting bodies to, uploading information to them, to blur and explore the relation human-computer-body-machine or cyborg as something floating.
