A canvas of empty glass shapes waits, pour in colour and watch a stained-glass mosaic light up.
The canvas generates a mosaic of shapes. Choose colours and paint the panels you like; the eyedropper picks up any colour already placed, and symmetry fill mirrors your strokes across the piece. When you're done, reveal the finished glass and save it.
Facet is original and draws on two crafts that solve the same problem differently: stained glass, where colour is held in lead-lined panels, and the mosaic, where an image is assembled from fragments that never blend.
Both build pictures out of bounded regions of flat colour, and that constraint is the point rather than a limitation — the divisions are load-bearing, and the image reads because of where the boundaries fall.
The canvas here generates the panels and leaves the colour entirely to you. The eyedropper and the symmetry fill are concessions to the screen — a glazier has neither — but the decision being made is the old one: which of these shapes should carry which colour so the whole thing lights up.
Facet is an original calming coloring toy in the relaxing creative-sandbox genre, a free browser game with no fail states, just colour and glass.
