The computer would be like a giant sandpit which you could "draw on" by pushing the grains around. It could respond using magnets to shift the sand itself.

Even make the grains with a piezo-electric polymer coating that changes colour for an added dimension!

Only problem is if they put it in their mouth, brings new meaning to user interface...
