Pin your favourite European masterpiece to your digital notice board. Discover Europe's cultural heritage on LCD screens at your gym or café. Create and share personal art guides on your smartphone. European web developers have come up with these ideas in a competition to create apps that expand the reach of Europeana, Europe's digital library, museum and archive. Participants in Hack4Europe 2012 developed new ways of sharing, re-using, creating or opening-up access to the 23 million digitised objects on www.europeana.eu . Their efforts showcase the social and business value of open cultural data in Europe. Awards were presented to winners of hackathons in Belgium, Latvia and Poland at the Digital Agenda Assembly in Brussels.
