The effect could be duplicated with students by snipping identical segments
of (gummed?) paper and gluing them in identical positions in the segments
of a circle.
In playing with this a minute ago, I tried another program for the first
Lotus Screen Cam-- http://www.lotuschannel.com/html/screencam.htm (Window
95/98) "Turn your PC into a VCR that records every click, scroll and
action on your screen." There's a 15 day free demo.
Alt+PrintScreen allows you to capture your screen image and paste it into
windows Paint or other graphics program, but Screen Cam records screen
activity and voice, if desired, for play back and allows it to be saved as
an editable movie file.
Has anyone used this in the art room? Seems to me that if any design,
painting or computer process can be done or diagramed on a computer, this
could be a most useful tool when demonstrating on a large screen in a class
setting. The file could be put on a disk and the steps could be played
back as many times as needed for self-directed lessons, for home work or
make up assignments.
Might be worth checking ...
