This idea reminds me of that Picasso video/photo where the little Spanish master is drawing a bull’s head or a face (I can’t remember what it was) in the air with something. Ok, I didn’t explain that properly, but those that have seen it will know what I mean!
“The four FRONT members have developed a method to materialize free hand sketches. They make it possible by using a unique method where two advanced techniques are combined. Pen strokes made in the air are recorded with Motion Capture and become 3D digital files; these are then materialized through Rapid Prototyping into real pieces of furniture.” Sketch Furniture
I think it would be great to use this technology to create sculpture, rather than the wobbly looking furniture they have made with it. I guess the furniture is a way of commercializing the idea.
