And before we did lasers...we did Light Boxes...
Background:
Back in '73 or so, I had a electrical engineer roommate that worked at TI. One evening he brought home what he described as the coolest thing he couldn't pass up from Neiman Marcus, a posh store in Dallas. He took it out of the bag and plugged it in. It was a white cube, about 10" on a side, solid on all 5 sides except the front, which had square cut-outs in three partitions, front to back. Each cut-out in the next partition toward the back got smaller. All cut-outs were centered on the center line of the box. It started flashing colors in each partition. And it looked very cool. I had to make one, but better. So I did, and this is what it looks like when you play music to it. The color changes are all random.
As an aside: I saw in another thread where it was discussed on YouTube would take down a posted video if it used commercial music. I've never had YouTube do more than provide an initial warning followed by, "your okay". I do not monetize any of my YouTube posts and maybe that is a factor, nor do I have a lot of "views". So well see from this post what happens.
Here it is, and I will post another of my laser YouTube vids in Laser Displays...shortly, that ties in with my thread "In the old days...this is what we did"
So here is light box magic. Doing one with DMX controls would be very cool (and I started building one back in 2017...sigh) but now I've diverted to exploring Programmable RGB LED strips.
Here is another example done at the same time as the first one, done to Steve Miller's "Abracadabra":
