A friend in another field sent me a spiral motion after effect demo program
that is very compelling. Neither he, nor the person who sent it to him,
know from whom or where the program came. I'd like to know so that I can
ask permission to use it as an instructional demo and so that I can give
appropriate credit if I do.
The program features a rotating, high contrast, sqare-wave spiral pattern
that changes direction twice. That is, the pattern changes direction, not
the rotation. That's all it does, one has to look away from the pattern to
see the MAE. (The instructions said look at your hand.) The executable
file is called Att131.exe. If anyone knows where this program came from,
please tell me. If it's part of a commercial software package, of course,
I'll cease and desist until I decide to buy the package.
Thanks,
Don
