Ages ago I made a foot-controlled scroll wheel, out of the guts of an old mouse and some printer parts. Today I'm doing some GreasePencil animation and it's proving really useful. The one thing that using a tablet doesn't give you is an easy scroll wheel control, which is used by Blender to control the size of the influence when using proportional editing. It would be best if you could map pen pressure to influence size, but this is a good compromise.
