Computer games for science? A good idea! That's what the team behind the Open Reassembly project at Graz University of Technology thought. In the game, citizen scientists become amateur archaeologists who reassemble an ancient artefact in several virtual rooms. In the current episode, Reinhold Preiner, Peter Houska and Stephan Karl explain the benefits of modern technology and computer-aided methods in archaeological research and how citizen science can facilitate the reconstruction of historical objects.
