[Lab] Touch sensitive/reactive windows

[Andrew O'Malley]

Thanks for the suggestion.

The other issue I have with an ir+camera solution is that there will
be substructure in the tower which will be holding all the lights
which illuminate the windows, so there will only about a 3 inch margin
between that and the inner walls.

ao.
