Another crude mockup using Photoshop, but I think you get the idea. I expect the final version to differ a bit from this, but this is a good start:
The bubblers change color, the Edison bulbs light, and the plasma sphere not only works, but is also sound sensitive. Vintage radio cloth is used to hide the speakers, and a Root Counter is placed under the DMD - the Counter is used to set the "date" that the time machine will travel to. Or I may use it to simply count games played. The water pressure gauges will not actually be functional. The upper box is the "generator" that makes time travel possible and features wire mesh backlit with LEDs.
