Peter McFarlane makes art with computers. No not on Photoshop, but with old circuitboards from garbaged PCs: 

To me, waste is just lack of imagination. This belief carries beyond the boundaries of my art production and permeates most aspects of my life. Most of my home and studio, and much of everything in them, is recycled. I’ve always had an epic imagination along with a driving desire to make things. Thus, used objects have pared my options down to a workable, manageable level.
