At our 2012 Future Day in Berlin Germany, we asked participants to write down their ideas and solutions for the future on “Bierdeckel” or coasters. We’ve compiled these ideas into a gallery.
Look through the ideas here and get inspired!
(captions are available in the flickr gallery)
If you have your own solutions to add, please leave them in the comments below or send us a tweet @FutureChall_org!
