I use the data projector in my computerlab/classroom's ceiling almost every day. Here's some things I like to do:
Since I teach Adobe CS4 (Photoshop, InDesign, Illustrator, etc.) I want to show all the tools and control panels clearly. The remote on the data projector has up/down buttons for "digital zoom" that zooms in on everything, including the controls, tools, and dialog boxes that would stay small when you enlarged the image. When I first started using it, I would forget to go back to "full screen", particularly if I was working off my workstation, which (at the time) was situated so that my back was to the projection screen.
I'll finish a PowerPoint show, and decide to show something else that requires digging. I press the "Freeze frame" on the remote, and leave the final image up while I go to the desktop or my doc's or whatever and find the next item. When it's up and ready, I click the remote again and show the current image.
I think that the transition of snapping off the lightswitch and plunging the room into darkness is abrupt and distracting. I also don't like fluorescent lighting, which is about all you have in classrooms. So I hung some big white ricepaper globes ("Chinese Lanterns") with warm incandescent bulbs from the ceiling, and use that as my normal classroom lighting. I can turn my data projector on and off without changing the lighting, and the students can still see their screens. The atmosphere is so much better than the overhead fluorescents.
