Free client-side apps by Vision Graphics: color, sound, geometry and light. No accounts, no uploads, no ads.
- PaletterOKLCH color palettes from twelve harmony methods, on a wheel.
- MusiccerChord wheel and music-theory sketchpad with MIDI export.
- BeatterSpin the world's great grooves out of two numbers — Euclidean rhythm circles with real drum synthesis.
- SpirallerGear-drawn rosettes — layer them, watch them draw, export for laser cutters.
- SunnerSun paths and shadows for any place on Earth — drag time around the wheel, watch shadows sweep your model.
- Vaultter4,000 years from arch to vault — spin the timeline, drop the keystone, raise the vault in 3D.
- WarmmerOne room re-lit from candlelight to overcast sky — spin the Kelvin wheel.
- LensserFocal length, aperture, distance and sensor on wheels — watch perspective and depth of field react live in 3D.
- ExtrudderTrace a floor plan, pull it up into 3D, take the model home.
- ViewwerSpin the 3D shape, spot its true flat view — the classic spatial-aptitude drill as a daily game.
- SliccerGuess the cross-section before the blade lands — conic sections free of charge.
- FoldderWhich net folds into this solid? Pick right, then watch it snap shut.
- CarvverReach the target shape in the fewest carves — boolean-op golf in 3D.
- RotatterSame or mirrored? Race the clock and plot your own Shepard–Metzler line.
- ShaddowerRead the sun's alibi — deduce the hour, the season and true north from shadows alone.
- BounccerBend real light: mirror, lens and prism puzzles with honest Snell's law.
- MixxerMix one color twice — with beams of light and with paint.
- DifferSpot the identical colors your eyes swear are different.
- FrammerTen-second composition drills — crop, place the horizon, hit the thirds. Or φ.
- EpiccerDraw a shape — watch spinning circles redraw it. Fourier series, made visible.
- CoggerGear-train puzzles — hit the target ratio and spin direction with the fewest gears.
- PendullerA Victorian drawing machine: tune pendulums to musical ratios and watch damped Lissajous figures spiral to rest.
- PlanetterThe real solar system on two wheels — scrub millennia of time, then dial the scale to honest and watch every poster's lie dissolve.
- TrusserBuild the bridge that survives the load with the least steel.
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.
