Thinking about a simple LCD sequencer control interface, it occurred to me
that if you had a LCD display flat on a table, with force sensors under each
corner, and applied a force vertically to the screen, then (remembering
vectors etc) you can work out 1. where on the screen you are pressing and 2.
how hard you are pressing.
Which could be good for a slider type interface, where you press is
determines which slider & how hard, the amount.
Plus you need a button to lock (or unlock) the slider when you are at it.

Don't know whether this would be useful, but it might suit someone. 
Indeed, it probably exists already.
