This announcement is worth repeating. Take a look at Tim Sneath's post here for a good write up. Then go check it out yourself at the British Library's home page. Always a treat to work for a company with great technology and then see it used for something truly useful.
I just spent some time looking at Leonardo DaVinci's Codex Leicester and am amazed. Who would have thought I would ever see anything but flat scans. Very nice page turning effects with shadowing, performance is good. Well performace is actually great if you consider I'd probably have to become a legitimate published scholar with tenure before anyone let me near this in the first place.
