What this is
Mosaic engine breaks a picture into flat cells and paints each one a single color. Delaunay triangulation decides where the triangles go: points are scattered over the image, then joined so that no point falls inside the circle drawn through any triangle's three corners, which keeps the triangles wide instead of sliver-thin. Voronoi is the same points read the other way round, one cell around each point holding the ground closest to it, and the other five modes lay hexagons, squares, diamonds, circles or bricks over the picture instead.
How to use it
- Choose or drop an image, or keep the sample.
- Pick a preset or a tessellation, then set the cell count and the edge weight.
- Add a stroke, choose a fill and an animation, then save a PNG or copy it.

Common questions
Does it need WebGL or a strong graphics card?
No. It draws on a plain 2D canvas, so any current browser can run it. Big cell counts need a fast processor, not a graphics card.
Is my picture uploaded?
No. The picture is read and broken up on your device and never leaves it.
Why is a picture from another tool here?
Pictures you add are kept on this device for every lab tool that takes one, so you need not add them again. Press × on a tile to forget that picture; the sample comes back.
Why does the video stop by itself?
Record video keeps exactly one sweep, Seconds a cycle long, so the clip loops when it plays. It is an MP4 in H.264, the kind phones, Photos and Instagram play.
