I upgraded my flickr account to Pro status today (more photos coming soon!) and ran across a really cool screensaver that pulls photos down from flickr. You can specify who you want the photos to come from, what tags you want, groups, yada, yada.
It’s called Slickr and can be downloaded here. The nice thing is that you don’t have to have a flickr account or anything. You just tell it what kind of photos to download.
I’ve actually had trouble coming back to my desk and ‘ending the show’ in order to get work done. My kids are so dang cute.
