Sadly, MS has dropped the Active Desktop in Vista just when it was catching on. What I'd pay a bounty for would be a small app that replicates the ability to show 'active' content on my Vista desktop.
I've seen some free/shareware programs that aim to do the AD thing, among other features, but I've yet to be able to do it painlessly.
What I'm looking for in specific is the ability to view web pages on my desktop (for looping weather .gifs/.jpgs). This app should allow for the customization of the pages, i.e., resizing and moving to different locations on my desktop.
Feel free to ask any additional questions,
Here is a picture of AD in XP:
