How to see the original lightsim:

    cd lightsim

    python lightsim.py

    Play with sliders.

How to see the new lightsim:

    Start 3 shells, and in each one set this:

      export LIGHT9_SHOW=/path/to/light9/show/dance2008

    You may need a 'chmod 755 bin/*' if this is a new darcs checkout.

    Shell 1:

      bin/dmxserver --dummy

    Shell 2:

      bin/keyboardcomposer --no-sliders

    Shell 3:

      bin/lightsim

      (it spews tons of Qt stderr, unfortunately)

    In the keyboardcomposer GUI, bring up any combination of these subs:

      house

      midleft

      midright

      red

      orange

      green

    As you adjust subs, lightsim should rerender its combination of

    channel photos. I didn't have any properly-photographed lights, so

    all you get are some lousy hand-painted lights on a single photo.
