The 3.5.4 version of polygen for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X is an intellectual property of Bartlomiej Niemtur. Polygen for Mac lies within Design & Photo Tools, more precisely Viewers & Editors. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.
From the developer:
polygen lets you create abstract wallpapers and photo-based crystal patterns, automatically or by hand. PolyGen patterns are ready to be used as mobile or desktop wallpapers, avatars, or social media backgrounds. Low Poly abstract patterns come with a unique and eye-catching style.
You may want to check out more software for Mac, such as iPodEditor, OnTheAirCGServer or Flickr Widget, which might be similar to polygen.
