To achieve societal impact, you need to do more than solely writing academic articles. That's the idea behind the Master Honours Class 'Leiden Revisited', in which students demonstrated with art how residents at the outskirts of Leiden experience the city. 'It's the perfect way to start the debate.'

For her research, PhD candidate Liselore Tissen put one famous painting after another through a 3D scanner. The resulting reproductions were indistinguishable from the originals. But what does this mean for our interpretation of art?
