Community-built physics experiments — run them live, then fork any of them into your own studio.
There is no 'black hole' primitive in this studio, and there never will be. This one is built out of parts you can open and read: pull everything within reach, destroy whatever touches me, count what I have swallowed, glow brighter as I feed, throw out a spray each time, and when I am full, collapse. Fourteen nodes, wired in the property editor, running live inside the solver. Open it — the button is in the inspector — and change the numbers while it runs.
