Someone has posted a daily log of PR changes to several sites. This log is interesting only in the fact that you can see, at a glance, the periods when PR changes have taken place. Notice that in some instances, the PR update is not across the board, which we see evidence of from time to time on forums, where someone posts that PR is updating for them, but no one else sees an update. Scan through the the log here and look for the red blocks, which indicate a change in PageRank. This log will not change in your life in any way, but it is simply a nice visual that I thought might be interesting especially to SEO newbies who have not seen a lot of PR updates yet.
