Starting with three.js for a simple, javascript-based, 3d game in the browser. If you’re interested in the library, you can find it here: https://github.com/mrdoob/three.js/ It’s one of my favorite libs to play with for quick, simple 3d animations. First gif of progress (It’s a simple blocky car being controlled via wasd):

I’m sort of making this up as I go, but the final product will probably involve cars, or some kind of flying craft. I’ll fit the theme in somehow, lol.

Good luck!
