Metapixel is an application I wrote for creating photomosaics. It’s Free Software and if you run Ubuntu or Debian all you have to do to install it is type “apt-get install metapixel“, so give it a try!
A few days ago I got an email from the Hamburg, Germany based software development house freiheit.com that they’ve written a server application around Metapixel for a web-based photomosaic-creation application for the German company Otto Versand. You can upload your photo and it’ll build a mosaic out of photos of stuff you can buy there – pretty neat. There’s also a few mosaics of minor celebrities which you can browse and inspect in detail.
By the way: freiheit.com is looking for competent software developers willing to work in Hamburg!
