A physics machine you scrub with the scroll bar: a red ball rolls across every Labs app.
Every app, in order
The machine jammed This browser rounded the physics differently and the ball got stuck, so here is the plain list instead.
Same list, no physics required. Classic view with filters and search →
- Paletter (opens in a new tab)OKLCH color palettes from twelve harmony methods, on a wheel.
- Musiccer (opens in a new tab)Chord wheel and music-theory sketchpad with MIDI export.
- Beatter (opens in a new tab)Spin the world's great grooves out of two numbers — Euclidean rhythm circles with real drum synthesis.
- Spiraller (opens in a new tab)Gear-drawn rosettes — layer them, watch them draw, export for laser cutters.
- Sunner (opens in a new tab)Sun paths and shadows for any place on Earth — drag time around the wheel, watch shadows sweep your model.
- Vaultter (opens in a new tab)4,000 years from arch to vault — spin the timeline, drop the keystone, raise the vault in 3D.
- Warmmer (opens in a new tab)One room re-lit from candlelight to overcast sky — spin the Kelvin wheel.
- Lensser (opens in a new tab)Focal length, aperture, distance and sensor on wheels — watch perspective and depth of field react live in 3D.
- Extrudder (opens in a new tab)Trace a floor plan, pull it up into 3D, take the model home.
- Viewwer (opens in a new tab)Spin the 3D shape, spot its true flat view — the classic spatial-aptitude drill as a daily game.
- Sliccer (opens in a new tab)Guess the cross-section before the blade lands — conic sections free of charge.
- Foldder (opens in a new tab)Which net folds into this solid? Pick right, then watch it snap shut.
- Carvver (opens in a new tab)Reach the target shape in the fewest strokes — boolean-op golf in 3D.
- Rotatter (opens in a new tab)Same or mirrored? Race the clock and plot your own Shepard–Metzler line.
- Shaddower (opens in a new tab)Read the sun's alibi — deduce the hour, the season and true north from shadows alone.
- Bounccer (opens in a new tab)Bend real light: mirror, lens and prism puzzles with honest Snell's law.
- Mixxer (opens in a new tab)Mix one color twice — with beams of light and with paint.
- Differ (opens in a new tab)Spot the identical colors your eyes swear are different.
- Frammer (opens in a new tab)Ten-second composition drills — crop, place the horizon, hit the thirds. Or φ.
- Epiccer (opens in a new tab)Draw a shape — watch spinning circles redraw it. Fourier series, made visible.
- Cogger (opens in a new tab)Gear-train puzzles — hit the target ratio and spin direction with the fewest gears.
- Penduller (opens in a new tab)A Victorian drawing machine: tune pendulums to musical ratios and watch damped Lissajous figures spiral to rest.
- Planetter (opens in a new tab)The real solar system on two wheels — scrub millennia of time, then dial the scale to honest and watch every poster's lie dissolve.
- Trusser (opens in a new tab)Build the bridge that survives the load with the least steel.
- Gearwalkker (opens in a new tab)Jump gear to gear on a real tooth-ratio — ride the rim, dodge the mesh point.
- Swingger (opens in a new tab)Grapple-swing on a real pendulum — short rope, quick tick; long rope, slow tock.
- Ptolemmer (opens in a new tab)Jump the deferent and the epicycle — read the loop before it goes retrograde.
- Toppler (opens in a new tab)Fourteen physics games — dominoes, a wrecking ball, a cannon, a ragdoll — on a budget of shots.
Why free?
Because these are the toys I wanted to exist. I run a small 3D visualization and AI development studio in Hungary; these apps are made of the same skills — light, color, geometry, sound — just small enough to give away. Everything runs in your browser: nothing is uploaded, there are no accounts, no ads, no tracking. If one of these makes you want the full-scale version of that competence — a real building visualized, a real tool built — that’s what the studio does. If not, enjoy the toys.
