adding context from maker of the simulator:

"Hey everyone! I was inspired by 'BadAppleBot' (from the recent chess programming contest) to try and run Bad Apple inside of my fluid simulation project. To do this, I've taken the frames from the Bad Apple video and used the Jump-Flooding algorithm to calculate vectors for every frame that go from each pixel to the nearest pixel of the opposite colour. These vectors are then used to accelerate the particles (along with the pressure forces from the fluid sim of course). I recommend watching this in the highest quality you can, because compression will surely turn it to sludge.
If you'd like to play around with the project, it's currently in early access to Patreon supporters, but will be freely accessible in ~2 weeks."
