For anybody who's new to this blog, the "Friday Fun Link" is something that I've been doing in one form or another since the late 1990's.  It began when I compiled the Saskatchewan Publisher's Group's semi-monthly electronic newsletter, SaskF@cts.  I added a section to highlight interesting, relevant or unique web sites for our members.  When I moved to Alberta and worked for the Writers Guild of Alberta, I resurrected the idea after setting up a listserv for that organization's members and it officially became the "Friday Fun Link".  When I came to library school, I was asked by a fellow student to help out with LibrarianActivist.org and that provided a good opportunity to resurrect the idea once more.  I also cross-post the Friday Fun Links on my blog (to make my attempts to post on a daily basis a bit easier, at least once per week.) 

Here's this week's FFL:

Do you ever have one of those moments where your mind briefly conceptualizes some gigantic idea? This illustration of the population of the earth using pixels had the same effect for me. (via Digg)
