Has anyone used Gumby Framework? This seems to be a fork of Foundation with added features like Responsive Images, Toggles & Switches, Fancy Tiles, Shuffle etc. It has flexible Grid where you can change the columns from 12 columns to any number you like or embed a grid within a grid. Also the grids seem to be not restricted to 960px. I would like to know if anyone has used it and if so how was your experience? Do the extra features make a big difference? How does it fare against bootstrap?
