Let's get a desktop thread going!
Post your current desktop (No cleaning!!!) and we will rate and help you with recommendations for making it beautiful.

I'd recommend the following for Windows:
Rope off your desktop
Fences allows you to create shaded areas on your desktop that you can place icons in. You can label them however you wish, and move/resize them anywhere on the desktop. Pre-included layouts help speed the process for new users.
See your wallpaper again! Quickly hide & show all your icons with an easy double-click
Double click blank space on your desktop, and all your icons will fade out. Double click again, and they’ll return. We think this feature is so useful and unique, that we’ve applied for a patent on it. You can even pick icons and individual Fences to exclude!
Create snapshots, and have automatic scaling (for screen size changes)
Take and restore snapshots of your Fence layouts for backup, or for when you are doing different tasks. Change your resolution for playing games and Fences will keep them in the same relative spots. In the Pro version of Fences, the "snapshot" feature has been enhanced to automatically take and keep recent snapshots on hand, ensuring your desktop layout never gets lost.
Rainlendar is a customizable calendar application which stays out of your way
but keeps all your important events and tasks always visible on your desktop.
Rainmeter displays customizable skins, like memory and battery power, RSS feeds and weather forecasts, right on your desktop. Many skins are even functional: they can record your notes and to-do lists, launch your favorite applications, and control your media player - all in a clean, unobtrusive interface that you can rearrange and customize to your liking. Rainmeter is at once an application and a toolkit. You are only limited by your imagination and creativity.
ObjectDock basically gives you a nicer task bar. On Win7 you cannot completely get rid of the task bar with any of this software, but you can hide it (and it rarely pops up).
You can have anything from a nice Mac look bar to anything you desire.
For various skins and themes for these programmes, you can find them at Customize.org - There's also plenty on DeviantArt to my knowledge!
I don't make full use of Rainlendar and Fences, but they are handy to have if you like to keep desktop icons etc. and keep organised for those of us who have busy lifestyles.
I can't say much for Mac as I don't use one and their look is pretty slick anyway.
Most Propaganda is taken from the websites - I'll help as much as I can with issues, but I'm new to this myself!
Anyway, happy clearing of desktops to you - It'll feel better when you join the clean Desktop master race!
