Ben Hammersley has been at DLD (an invite only conference). He has started to share the link goodness on his blog. There is some great stuff in here only a couple of which I have heard of before (YouAreNotHere was done by students from the NYU ITC course, some of them were at ETel last year to demonstrate some of their projects including Botanicalls).

One that is very interesting is 19.20.21, not sure what the background is, but the flash site has some nice visualisations of global data. It will be interesting to find out more about them.
