Free client-side apps by Vision Graphics: color, sound, geometry, light and physics — tools, toys and daily games. No accounts, no uploads, no ads.
- 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.
