Firefox only (Windows/Mac/Linux): The Flickr Gallery Plus Firefox extension or Greasemonkey script make browsing galleries faster and easier in Flickr.
Once installed and set up, Flickr Gallery Plus automatically grabs larger versions of each image in a set so you can view each picture waiting for another page to load. It even turns sets into nice slideshows that fade between photos. Like to navigate photos from the keyboard? You can advance between images with the right and left keys.
If you're a Flickr junkie, Flickr Gallery Plus is a great add-on to view Flickr sets. For more spicy Flickr improvements, check out our very own Better Flickr Firefox extension. Flickr Gallery Plus is available in both Greasemonkey script form and as an experimental Firefox extension (that means it hasn't been vetted by the folks at Mozilla yet and you need to log in to download it), works wherever Firefox does.

To begin with, it's got a beautiful interface. Tracking your weight isn't a particularly fun activity, but Weightbot makes it seem pretty cool. 
The application includes gorgeous graphs displaying your progress by week, month, and year, your information is backed up online over a secure connection, and you can set a goal weight so you can watch your weight slope toward the finish line. 
If you want to prevent prying eyes from spying your weight, you can also set a passcode on the app.
