BallTok
Viral bouncing-ball videos in five minutes.

1080×1920 exports
Creators pick a mode — classic, destruction, collision, accumulation or spiral — tune colours, sizes and sound, and BallTok renders a 9:16, 60 fps video ready to post. A deterministic engine makes every render reproducible, and a server-side renderer produces the final MP4.
The problem
- Satisfying physics videos are a proven short-form format, but producing them means writing code or wrestling with After Effects.
The Tellter answer
- A browser editor on a deterministic physics engine, with server-side rendering for clean 1080×1920 exports.
