Bill Buxton's NotesThis device is one of the early examples that I encountered of tangible computing and phycons being used in industry. When BMW was designing the new Mini, they had a light-table type of tablet surface on which they put these models. By moving the position and angle of the phycon, or proxie, the full-size virtual model being projected on the power wall moved accordingly. It was a kind of worlds in miniature approach. This is one of the cars.
