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.
