An infinite physics whiteboard

Draw it.
It comes alive.

Sketch a shape and it drops, rolls, and tumbles for real. Paint, build ramps, blow wind, flip gravity — or draw with your bare hands. No goals. No losing. Just play.

funzone · draw it, it comes alive
everything is possible

A blank canvas where physics is the paint.

FunZone borrows the best from Crayon Physics, Line Rider, and sandbox toys — then makes it web-native, elegant, and endlessly playful. Here's what's under your crayon.

✏️

Draw anything, it's real

Closed shape → a solid that falls. A line → a plank or ramp. A quick tap → a bouncy ball. Every doodle obeys gravity the instant you lift your pen.

📌

Build & tinker

Pin a stroke to hang it in mid-air and make bowls, funnels, and ramps. Drop fountains that spout marbles. Assemble little machines that just… go.

Play with your hands

Flip on hand tracking and your fingertip becomes the crayon. Pinch to draw, open your palm to blow a gust of wind. No controller — just you.

🎵

It always sounds lovely

Every collision is a marimba note, tuned to a scale so nothing ever clashes. A soft ambient pad breathes underneath. Your mess makes music.

no download, no catch

Yes — the real thing, right here.

This is the actual FunZone, embedded live. Pick the ✏️ tool and scribble a shape. Watch it fall. Then open the full playground for the whole toybox.

the one simple rule

Whatever you draw becomes what it looks like.

01

Close a loop → a solid

Circles, blobs, stars, hearts. If it encloses a space, it drops in as one chunky, tumbling object.

02〰️

Open a line → a plank

Curves keep their shape as a bendy noodle. Pin it and you've got a ramp, a see-saw, or a catch-all bowl.

03🔴

Tap → a bouncy ball

A quick dot drops a springy marble in your chosen crayon color. Great for filling a funnel fast.

your toybox

Six tools. Endless afternoons.

✏️ Draw make it real 🖌️ Paint decorate the board Grab pick up & fling 🌬️ Wind push it around Fountain spout marbles 🧽 Erase poof, gone 🙃 Flip gravity 🐢 Slow-mo 🎉 Confetti
sound is half the fun

Every crash is in tune.

FunZone's audio is generated live and locked to a pentatonic scale — so a chaotic avalanche of shapes plays like a wind chime, never noise. Big objects ring low, little ones sparkle high, and a gentle pad hums beneath it all. Turn it up.

No goals. No score.
No losing.

FunZone isn't a game you win — it's a place you play. Kids, creatives, tinkerers: come make a beautiful mess, knock it all down, and build it again.
