Geez, some people have such great ideas.

This post over at GetLoFi.com highlighting an audio sampler made from laser cut cardboard and silk-screened conductive paint got me thinking… has anyone developed an electrically conductive glaze? Seems pretty simple — an iron rich glaze, maybe with some silver? Then you could run low voltage through it to light LED’s, run speakers, attach motion sensors, etc. Man, I’m salivating. Let’s fabricate this idea!
