I've been searching these for past one month or so but I failed to find anything that can be used without modification. 1. Hacker News Clone in PHP that can be easily integrated with wordpress/buddypress through a plugin. 2. Good event management plugin for wordpress/buddypress Apart from that I have some other ideas too: 1. Draw&Share Mobile App - let users draw freehand drawing using touch screen and share it with friends(on facebook, mms, etc) 2. Collaborative Whiteboard Web App - A simple whiteboard(freehand drawing + image/text/video/audio embedd) + Chat(text/audio/video) 3. UI Library that uses HTML 5 canvas instead of normal html/css/js controls.
