My LAC host Jonas Hielscher just showed me this nifty controller
called the Gametrak:

You get two 3D joysticks that are controlled by attaching a tensioned
wire to your hands (or whatever really). It gives you high
resolution data (12bit 0-4091) and you can really move fast and freely.

Has anyone tried anything with one of these? I am planning on
ordering one.

If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an
idea, which an individual may exclusively possess as long as he keeps
it to himself; but the moment it is divulged, it forces itself into
the possession of everyone, and the receiver cannot dispossess
himself of it. - Thomas Jefferson
