I teach Processing to grade 7 and 8 students at an international school and have often used  http://sketchpad.cc/ as a way for my students to share their projects on their ePortfolios (upload and embed) but it seems that the site is down and has been for a while.  Does anyone know what happened (and if it's possible to retrieve our old projects...)  Since it's based on etherpad, is the code available?  (I know openprocessing is still a possibility, but I was just wondering about other options.
