Satisfying physics clips,
recorded in your browser
Tweakable physics toys that render at full 1080×1920 or 1920×1080, play a rising note on every bounce, and record themselves straight to MP4, video and audio in one file, ready to cut.
Open the full studio and change anything. Play and record need a plan.

Not a video. That's the actual simulation, rendering in your browser at this moment. The rings crack open on a timer, the ball hunts the gap, and every bounce fires the next note of a rising scale.
Recording captures exactly what you see, plus the audio, into one MP4 at 1080×1920 or 1920×1080.
Open the studioEvery knob, not just a play button
Each toy exposes its own physics. Change something and the frame updates as you drag. No waiting, no re-render.
Built for Shorts
Switch between 9:16 and 16:9 and the simulation rebuilds for the new bounds, so nothing stretches or crops.
One-click recording
Records the canvas and the generated audio into a single MP4. No screen capture, no cropping, no watermark.
Sound that climbs
Every collision fires the next note of a rising scale, then loops. The rhythm comes from the physics itself.
Tune everything
Speed, size, gravity, growth per hit, ring counts, jelly stiffness. Adjust it live and watch it change.
Your own palette
Six presets plus full control of colours, neon glow, trails and line weight, all saved so your clips stay on-brand.
Nothing to install
