Cool.  What if you make a QT movie and post it somewhere?

Englebart's idea finally became a production reality with the Xerox PARC
machines in the 70's. I think that's where Jobs first saw it, when Apple
asked IDEO, Inc. to design a cleaner, more efficient, stable, and cheaper
device for the LISA, which they did. That same basic wheel-and-ball solution
is still being used in virtually all mechanical mice today, AFAIK.

But now, even my trackball is giving my poor CTS wrists problems. I need a
vertical trackball device, but I haven't seen what I want yet. I may build
my own from parts.
