Disappearing Act
(Inspired by the Exploratorium's "Seeing" exhibit)

Run the "Disappearing Act" program on your PC and watch an object disappear from sight, even though it remains in full view!

*[A "File Download" dialog box will appear, asking you if
you want to "Run the program from its current location" or
"Save the program to disk." You may select either option.]

Pressing any key toggles movement on/off. Pressing the "Esc" key terminates the program.

"Always remember to keep an open mind and question everything ... especially the self-evident..."

(... and, speaking of which, I'd like to hear your comments about this video.)

Goodbye for now . . .
