Art Historians Want Side-By-Side PowerPoint, Lament the End of Kodak Carousels

My friend the Art Historian tells me that Kodak has announced that they will cease manufacture of slide carrousels, much to the chagrin of thousands of museums and colleges. He also says that there is a multimillion-dollar market for a presentation program that can show, side-by-side, two randomly-accessed images (i.e., "Let's compare a Manet on the left with a Monet on the right"). He says it would be dead-simple to market, since the art-history world is so small. I'm long past the days of being tempted by speculative programming, no matter how trivial the application or lock-sure the profit. If you want to program such an app, let me know and I'll put you in touch with him.
