An "author cloud" takes your LibraryThing.com collection (mine currently featuring slightly over two thousand books) and lists all the authors, with font sizes increasing in accordance with how many titles one has by that author. While not being among those in the largest point sizes, Gurdjieff, Ouspensky, and Bennett are certainly notable on this (you can click on the image for a full-size version that's easier to read).
Anyway, while I was poking around there I got the idea that it might be fun to do a screen-grab (or, in this case, four screen grabs and some cut-and-pasting) and show it off in here. This is one of the more amusing "toys" over on LibraryThing.com ... you should check it out!
