Mossaik is a small browser tool for generating abstract SVG backgrounds — wave patterns and color-spin compositions — that you can drop into website hero sections, presentations, mobile mockups, or as a desktop wallpaper. You control the number of waves, angle, color palette, and gradient mode, then export the SVG.

It's a one-page editor, free to use, focused on a single design problem (decorative SVG fills) — the kind of utility designers bookmark instead of redrawing waves from scratch in Figma.
