Now this of course is perfect a perfect applications for distance students! Though I wonder how well it will translate to less visual areas (the example is of an art collection, which to my one-dimensional brain would seem much easier to work with than, say, the ERIC database). Sounds a bit like Grokker, too. Hey, I didn't realize Grokker actually had a product to sell finally! I tried the beta a while back and found it an interesting idea - guess I'll download the version 2 trial and see what's been improved.
