I'm a heavy KDE user but I keep switching DEs and WMs every now and then. Currently I'm playing with Enlightenment which is as pretty as it always has been. More importantly, it starts up on my aging laptop in less than 2 seconds, which is years ahead of both Gnome and KDE. As another lightweight but full-fledged alternative to the big two, I recommend it highly.
While this is a very interesting finding, I think the hermit crab's use of empty snails' shells is an already known example of similar tool use in an invertebrate.
