Sorry, no wordy description of how I did it at this time. Is a toss up for some guy on the net who's probably moved on to a different task by now. As I'm mostly a novice I don't even know if this is the best way to solve the problem. I suspect that if you want to do many more than three, the tree structure that results from this would start to get hard to manage very quickly.
The projection on the wall is handled by the spot light w/ a projector map. The slides I use are just JPEGs, but any valid 3ds visible map type should work. I did a test with an avi for the first slide. Worked fine, as expected. The wipes are handled by a mix map mixing two slides with an animated mix. I used a noise map for the first wipe and a simple gradiant for the second one. This makes it fairly easy to go into track view to change the timing of the wipe.
The one probably non-intuitive thing is the final mix map used to append each slide pair.
I think I've named the various maps so that it's sorta easy to follow them. I think I've arranged them in the material editor so that it's sorta easy to follow them.
I'd write more, but I have a ton of stuff I need to get done today and I don't even know if the first thing on which all the others rest is something I can do. Feel free to write with questions and corrections and faint praise.
Oh yeah, right, the project and stuff is all in the zip file... (max 4.2)
