A cool idea I used was to use 4 blinking jacolantern from the dollar store and take them apart and fasten them to the inside of your cyclatron like this.
I also put velcro under the pan so it was easily removable and I could change batteries. I also used a clear red flexable 3 ring binder that was clear and red for the red color. I cut the folder with scissors to get it to the right size.
They all blink in random order so if you turn all switches right after the other, they are random, but blink all around, kinda like the movie. The closest I could find for $4.
