Instagram.css - Pure CSS Instagram filters. You can add all these Instagram-like filters to your photos with using CSS only.
Taking the idea of CSSgram and building it into one master scss file with many variables for compiling as a single CSS file is where CSSgram has lost out.
Instagram.css is excellent; however, I am interested to see what will happen about the launcher using Instagram (a trademarked name) in the name of this open source package.
