The record

Product: Mosaic Magnifique is an open source photomosaic generator.
Interface: The app is a GUI based application for generating photomosaics.
Grid preview: Grid Preview overlays the cell grid on the main image.
Grid editing: Users can give areas more or less detail or exclude them from the photomosaic.
Comparison modes: The app offers RGB Euclidean, CIE76, and CIEDE2000 image comparison formulas.
Cell shapes: Users can create custom cell shapes from an image and adjust spacing, offsets, flipping, and alternate spacing.
Repeat handling: Users can set a range for finding repeated images and a value added to difference calculations for each repeat in range.
Colour tools: Colour Visualisation compares colours in the image library and main image and lists colours that could improve the library for the current image.
GPU support: The app can use CUDA on a CUDA-capable GPU, and the maker says CIEDE2000 results are much faster with CUDA.
Background: The photomosaic background colour can be changed, including its alpha value.
Download: The repository README directs users to download a pre-built Windows app from the releases page.
Platform limit: The README says the current build is Windows-only and CUDA is currently supported only on Windows.
Release note: The releases page says the datapack contains an Image Library (.mil) and sample images for use as main images.
Creator background: The maker says Mosaic Magnifique began as their third-year project for a BSc in Computer Science at the University of Manchester.
