## What is DefragMosaic?

DefragMosaic turns your photos into animated mosaic art.

Select any photo from your library, mosaicify it into a grid of color tiles, then watch as the tiles sort themselves into a beautiful color gradient — like a puzzle solving itself.

-- FEATURES --
• Grid sizes from 8×8 to 256×256 tiles
• Sort order: Light → Dark or Dark → Light
• Smooth animation with pause, resume, and stop controls
• Reverse playback to watch the mosaic reassemble

-- PREMIUM --
Unlock advanced controls with a one-time purchase:
• Tile Motion — All at Once: every tile moves simultaneously for a dynamic effect / Swap: tiles trade places one pair at a time for a methodical sort
• Speed — Fast, Normal, or Slow animation
• Sort Color Basis — 8 criteria to choose from:
  · Hue (rainbow gradient)
  · Brightness (light to dark)
  · Saturation (vivid to dull)
  · HSB Combined
  · Lab Lightness (perceptually uniform)
  · From Gray (distance from gray)
  · Hilbert curve (smooth color transitions)
  · PCA (image-specific dominant color axis)

-- TIPS --
Photos with a wide range of colors produce the most striking gradients. Try portraits, landscapes, and cityscapes for different effects.
