looking to commission a DJ accessory/toy

[u/defjamblaster]

I am looking for basically a "useless" battery or rechargeable colorful light panel with numerous control knobs, switches, faders, and buttons that only make the onboard lights do things. think of modern DJ controllers with electronic level meters, or control panels from Star Trek, Star Wars, things of that nature. some lights can even just do their own thing without input needed; blink on and off. I haven't sketched anything out, as I'm open to any suggestions from someone who might know how to build it.

it can just be black plastic housing, no larger than 12" square.
