Create a tool that helps you organise a good evening. Mobile (webapp) for the evening itself and desktop for before and after. The administator (host) has the possibility to invite friends to join the evening or remove guests. Once the host decided to start the evening you can upload pictures, post status, or let them know you've arrived on the 'timewall'. Because it's not possible to upload mobile picture through the browser I've used the Flickr API to fix this. After the host finished the evening, every guest can post his score about the evening on mood en food. There's also a complete backend to change the evening preverences to your likes.
