BounceHarmony

Every video starts as one line.

These three did. Send us yours — if it works, we build it and post it.

Each ball has 3 seconds to escape
Center pad spawns a ball every hit
Two balls touch, both freeze

One rule is enough: what happens on every bounce, and what that leads to.

Write the idea — that's the part we need.

We'll tell you if yours gets posted, and send the occasional BounceHarmony update. Unsubscribe any time.

That doesn't look like an email address.

Your idea is in. One tap answers this.

How would you like to support BounceHarmony?

Every idea is read by a person. By sending one you let us build and post a video from it. We never sell or share your details — how we use what you send.
