Shopping - Phil's Rambling Rants — LiveJournal
The Apple MacBook laptop and the iPhoto that comes on it make a nifty slideshow (although I'm at a loss as to where mine grabbed the accompanying soundtrack: I'm CERTAIN it's not in my iTunes). I expect that it costs much more than you were planning on spending for this purpose, though.
On the other hand, Bob Tedrow uses it to very good effect to display the construction process for his concertinas at his booth at fairs & festivals. Incredibly intricate work, which is ultimately totally hidden within the finished product. The pictures as displayed by the slideshow are even more effective than a Powerpoint demonstration.
