A much cheaper way might have been to buy a couple of Novation Launchpads. 8x8 full RGB tactile buttons for 90€, MIDI-controllable. Four of those next to another for 16x16 at 360€ plus a little bit for cables and controller comes out at 1/3 the price

It would be larger (even with the mini), you’d have gaps between the four, and also the four middle buttons in each part have their corners clipped. But you can get illuminated buttons for less money: https://www.ebay.com/itm/173922115935

Looking at teardown images of the launchpad pcb, it might be possible to shave down the ground plane on the two non-button sides enough that you could mate them up with no bezel interfering.

This is fantastic. I happen to own a physical pong table. Everyone loves it. [0] There is something magical about material and only-does-one-thing instantiations of digital things. —— I am really looking forward to a flat table top screen consisting of millions of magnetically-controlled vertical-extruding rod pixels, with actual color controlled pixels along their length. For an amazing table display/extrusion of D&…

And optimize for repair when one of the thousands of actuators gets stuck or burns out…

Here’s a thought, though: you’ve seen the sand table + kinect projection mapping demo? What about that, plus a two-axis moving magnet sand mandala marble drawing table? The actuator could draw the path /sculpt the terrain, then release the marble and grab the figurines?

The size and button shape concerns would remain.

Conversely, it'd be cool to play it on an large empty office building. One window = one pixel.

Wow, in switches alone this would cost me $1200! Which actually isn't that bad for a one off-like this with easily available components - I've seen worse. You can of course take your chances with Aliexpress Specials but be warned: some of those cheap switches are cheap switches (sometimes, they're barely even switches). And you won't be getting them inside of 2 weeks.

I think I would have tried mechanical keyboarding switches that can take an LED and a clear keycap. Not really the same effect, but you could probably have gotten out to 24x24 for the same price.

I've always wanted something like this board, buttons which can light up (preferably a few colours), to use to make games. Anyone ever found such a board which is hackable / programmable?

There's custom firmware project for the Novation Launchpad.

I had a fork of this at one point where I made GoL for it and had mapped the lit cells to a MIDI output.

I haven't tried this yet, but there's also an open source grid-controller project.

When I was a teenager, I read a book about assembly language for the commodore and implemented the game of life in a really simple way. I just used the text screen. To switch on a cell, I would put an asterisk ('*') in it. Then I could run my machine code program and it would evolve according to the rules of the game of life.

When I got into retrocomputing a few years ago, I also did this. Works great with TRS-80 semigraphic characters. First, I wrote it in C with a Z80 c compiler. The, I wrote it again in assembly and it was much faster! Amazing!
