is the main
issue, since the larger the dome,
the larger the surface area the light from the projector must cover.

|Pixels per degree of sky

This past weekend, I stopped in my classroom to grab a test. While I was rooting through my files, I let my 9 year old daughter try out the [Digitarium] remote. She was able to do a lot of different tasks after only 15 minutes! This program is very user friendly - thank goodness, because I am NOT a computer whiz.
