After-hours Fun with Capacitors at Work?

Chiggy_Von_Richtoffe asks "Hey, Folks! I start a new job at a small manufacturing plant (capacitors and small run custom circuit boards) in a few days, which itself is kind of cool. What is even more cool is that their facilities include an electron microscope, programmable high temperature ovens (think kilns), rapid cooling chambers (liquid CO2) to test component robustness, a lapping machine, all the kinds of ceramics i can think off, as well as equipment for die cutting, electroplating, and a few other industry related tasks. This of course fills my mind with wicked designs for homebrew projects, but i am always looking for new ideas to try. Given this kind of workshop what sort of (non-destructive, and fully legal) DIY projects could you come up with?"
