A few months ago I wrote about a skin package to make Windows XP look just like Vista. That package changed everything from the boot screen to the gadget bar to give Windows XP just as much eye candy as Windows Vista. Well, almost. It still didn't offer the 3-D desktop that Vista offers.
No problemo, there is a utility that will give you the Vista 3D desktop option in Windows XP. It is called Winflip, and is absolutely free (Hey that rhymes). It allows you to display all of your open windows in a 3D way that looks just like the way Windows Vista does it.
There have been lots of articles written about it lately. This comment is taken from Free Download A Day:
WinFlip adds an interesting dimension to task switching. Rather than just using Alt + Tab to move through your open windows, it displays all your currently open application windows in a 3-D stack on your desktop. To change to a different window, you can use your mouse or keyboard to choose the desired application window. You can configure the look to use large or small images for your windows, and its relatively small footprint means that you won't bog your system down for just the aesthetics.
If you are still on a quest to have the Vista experience without the Vista crapiness, then Winflip is another application you can add to your arsenal.
