Mosaic turns your photo into a mosaic built from thousands of public-domain masterpieces from world museums. Zoom in like on a map and tap any painting to see its title, artist and museum. Three ways to use it: Photo mosaic: a high-resolution picture you can save and share. Video mosaic: watch the mosaic assemble itself. Hide & Seek: hide a tiny photo inside your mosaic and send a friend the link. Can they find it by zooming? Free for now, no sign-up. Works right in your browser.
