Evan, IN mad scientist's lair

I'm doing a small haunted house at my place and I'm wanting to do a reanimator-style lab. I'm looking for some wire frame anatomical modeling or some cool "process control" images to run on an older computer. We did a thing called ZombieTech at a Jaycees haunted house about 20 (Oh my God, has it been that long?) years ago and it was a huge hit. One of the things we used were some "diagnostic" screens that we had done with an Atari 520ST. Anyhoo, looking for some mad scientist stuff to run next to the Jacob's ladders and such.
