Tetris on RGB matrix

I build Tetris on Espruino and output it on a 16x8 RGB matrix. I'm controlling it work some push buttons which works well but I might build something better.

You can download the code here, it will work with most displays just change the Graphic settings at the top. There are still a few small bugs and lots of features I want to add.

Here is a quick video showing the game play (excuse the crappy paper diffuser but my camera can't focus on the LEDs without it)

That looks great! To be honest the paper diffuser still works pretty well :)

That's awesome. The diffuser isn't bad - you need some kind of diffuser, otherwise you can see the individual colors in each LED (like red/green dots inside the yellow). Vellum from art store is considerably better than straight up paper. It's a little clearer, looks more even, and less obviously cheap.

The diffuser (and frame around it) also lets you hide some super bright lights along the perimeter, which you could do a light show with (ie, a few bright flashes right after a tetris, making it harder to see the game action - this is legit tactic in arcade games, used very effectively in pinball)

Really, no need to excuse your paper difuser - your tetris gameplay, on the other hand... ;-)

@DrAzzy have you come across a decent way of getting/making a grid to go behind the diffuser? When we did it for the Word Clock it was a bit of a labour - it feels like there must be an easier way!

For this size, a 3d printer comes in mind. Or use a prismatic acrylic sheet with corresponding spacing (1/n of the led spacing). Should be nice without a grid.

Gorgeous. About control: Why not use a Wii Nunchuck? @Gordon made a perfect module for that ;-)
