Thanks to Darren at UCL for this: Reimagining the Future of Your Desktop in 3D. It’s a new way of rendering a desktop, using what they describe as the affordances of physical storage. So, you can heap documents in piles, scatter them, regroup them and so on, very easily. I liked the range of ways of browsing piles of documents and thought it looked like fun, but without using it for a while, can’t be sure that it would save me time in the long run. I fear it would entice me into spending even more time than I do already categorising and re-categorising documents when I should be reading them!
