[Frameworks] how to power a projector mounted on a rotating device

[Mani Mazinani]

Marco's machine looks wonderful.  Toronto artist John Shipman has
constructed what Scott is looking for an installation using slide
projectors.  It uses the slip ring things mentioned previously. His website
will have more information and his email address as well.

Best,
Mani
