Facet - Turn any photo into a wallpaper, with live Metal effects

Hi Product Hunt, I'm Fabio, I made Facet. I kept taking photos I loved and wanting them on my screens, but plain photos rarely make good wallpaper: too busy behind the icons. So I built a small studio that reshapes a photo into something calmer and more graphic. Facet has six effects, each one a real optical or print process rather than a filter: - Reeded and frosted glass, like looking through architectural glass. - Prism, real chromatic dispersion (ported from paper.design's shader). - Halftone and CMYK halftone, actual print dots with per-plate control. - Dithering, from 1-bit newsprint to Game Boy green. It's a native Metal engine, so the preview is live and full resolution while you drag the sliders. Sixty-plus presets to start from. Everything runs on your GPU, on device: no account, no analytics, no network access, your photos never leave. It's a universal app: one purchase of 2,99 € covers Mac, iPhone and iPad. No subscription. There's a free pack of 12 photos to try it on. One limit: the output is a static wallpaper. macOS has no public third-party API for live desktop wallpapers, so I make still images by design. Would love to know which effect you'd reach for first. Happy to answer anything.
