figure out projector set up

[julcor]

1. figure out which projector to use
2. figure out if we can do a two plinth set up
3. figure out if black background works
4. figure out if we should try projector sideways

[julcor]

1. which projector to use: black one in 3rd year room (short throw is too expensive!)
2. use a tripod instead of two plinth set up, allows for projector ventilation when sideways
3. black background works, although might not look as good. tbd on day of show based on light in cubbard
4. projector sideways is fine, but should be in brackets to allow ventilation from all sides
