Nate at Wasted Electrons points to an excellent site for PowerPoint:
Jim Placke's PowerPoint Humor page.
Sung to the tune of “The Wreck of the Edmund Fitzgerald
(And with all regrets to Gordon Lightfoot…)The legend lives on from the Fifth Corps on down,
of the thirty meg PowerPoint briefing.
The software its said never gives up its dead,
when the God of Electrons grows angry.
With officers galore, maybe a hundred or more,
it was said that no one could outbrief them.
The good ACE and crew was a bone to be chewed,
when the God of Electrons came calling.
Lots more at the site including this great quote:
“If your words or images are not on point, making them dance in color won't make them relevant.”
