I'm not willing to accept the excuse that because it's in PowerPoint we can't make it look good or that we're limited in some way. Ever since David Byrne took a turn at creating art in PowerPoint, I've liked the idea of embracing it as a challenge. If people can manage to create art on something like an Etch-a-Sketch, PowerPoint shouldnt prove a barrier to creativity. Anyway, there really are no limitations, pages can get formatted in any aspect ratio you like, color is as limited as RGB, animation keeps stepping up, and clever use of it can get you close to the elegance of credits in a high-budget, Hollywood flick. And, if and when you do feel a creative pinch just import: movies, eps, png. There are really no excuses for not produce any visual experience with whats available in PowerPoint.
