Unfinished instrument (Nat Chard)

This was an attempt to repeat the performance of Instrument Two in real time, so the projection would be a durational one, drawing with moving points of light onto a photosensitive paper on a moving folding picture plane. It still sits in this state, as it became clear that the predictability of light projection was too predictable for my needs. It uses identical cast aluminium components as Instrument Two (and Three, yet to come on here) but the active parts are completely different. The large roller bearing is to carry the picture plane, also located by the small bearing on top of the tower.
