A Sprig Games experiment · partially educational, definitely weird
The camera shows you a pose. You copy it. It grades you, joint by joint, on exactly how badly you flailed. But can you do this?
The warm-up
Hold still. Can you nail it?
One pose, dead-on. The camera reads your joints and grades how close you got — with a per-limb report card that knows exactly where you cheated.
The main event
It's moving now. Keep up.
Timed routines — a dance to flow with, a golf swing to time. A ghost skeleton leads; you chase. Score every frame or just the moments that matter.
Your move
Think you've got a harder one?
Drop in any video. We bake its movement on-device, set it side-by-side, and dare you to match it. Nothing leaves your browser.
01
A pose tracker runs entirely in your browser, reading the angle of every joint in real time.
02
Your skeleton is lined up against the target and scored limb by limb — off by a few degrees, off by a mile.
03
A live accuracy score, a color-coded overlay, and the one joint that gave you away.
