Gameplay/Demonstration OE-CAKE lives again. I rebuilt it for the browser: Classic interface, your old .oec files import, free, no install. Brand new life!

Hi there! if you're in this sub, you already know: the best physics toy ever made died in 2008, and nothing ever replaced it! Phyzios Studio is amazing, but it’s not quite as intuitive for anyone to pick up and play with.

I couldn't let that stand. I spent the last few months rebuilding it:
Introducing SunaBox! (sunabox.dev)

What is SunaBox?:
(Besides a pun? Sunaba = Japanese for “Sandbox”!, like “oekaki” is Japanese for “draw!” All love to Prometech and OE-CAKE!)

  • A complete, clean-room reimplementation of OE-CAKE, with a brand new physics engine, that runs in your browser. 
  • A 1:1 recreation of the classic interface. Select Classic at the top and it's 2007 again. Same panels, same materials, as close to the same feel as I could manage.
  • Your old .oec files import directly. If you still have creations from fifteen years ago, they open. I would love to see what this sub still has in its drawers.
  • The classics: water, oil, rice, tar, gas, fire, steam, rubber, string, walls, wheels, the dropper. Plus some new toys the original never got: lava that quenches into stone, fireworks that bloom in their own colors, orbies (orbeez), popcorn, and more.
  • And one thing 2007 could not do: the engine is bit-deterministic, so you can record a session and share it as a file that replays identically on any machine, scrubbed back and forth like video. With beautiful new visuals/shaders and enormous performance gains.

.OEC file behavior parity with the original game is around 93% by my own judgment, and this community is the world authority on the last 7%. If something feels wrong, tell me exactly what, ideally with the .OEC that shows it. (Or a .sunar replay!)

I fix feel bugs weekly and every fix ships with a test so it cannot regress. This is built with an AI pair programmer doing the math. The taste and the love are mine. Free, no account, runs in any WebGPU browser! SunaBox is for everyone who kept OE-CAKE alive in their hearts all these years. (:

is it more performant? will you expose more of the information of the sim and materials to the user? will you add materials and ideas?

Compared to OE-CAKE, yes, the performance here is MUCH better!
As for improvements, absolutely! I'm open to any and all ideas to improve the engine and sandbox; I want this game to belong to the community.

Aw man they vibecoded my forgotten obscure physics simulation sandbox. There's just no refuge.

[aether] no WebGPU adapter

WebGPU is unavailable. Check chrome://gpu, or that this is Chrome 113+ / Edge 113+ / Safari 18+ with hardware acceleration enabled.

dawg what if my gpu is too old for ts
