April Fool's PowerPoint?
For April Fool Fun with PowerPoint, try this easy trick in misdirection. Visit http://www.johnsleigh.com.au/CardTrick.htm , download the two slides, and follow the simple set-up procedure.
It's a sly twist on an old mind-reading, card trick joke. And while it may be worth an eye-roll, grimace, or groan from your audience -- this two-slide presentation can also serve as an amusing lead-in for a discussion on assumptions or taking symbols for granted.
It's G-Rated fun -- try it, you'll like it!
