Animated Desktop
Want to use your motion screensaver as a wallpaper? Using Animated Desktop you can emulate the functionality of Vista Ultimate DreamScene (video screensaver) both on Windows XP and Vista Home edition. If you’re planning on getting it, I highly recommend to use it together with the previously mentioned Rocketdock.
Volumouse
Another cool program you should definitely check out. Volumouse provides you with a quick way to control the volume on your system by using your mouse wheel. It lets you define a set of events when the wheel will be used for changing volume, i.e. when the Alt key is hold down, when the mouse cursor is over the taskbar, etc. It doesn’t interfere with exisitng mouse functionalities.
CursorFX
This little app lets you choose between incredibly cool looking Windows mouse cursor themes. You can either select one of the default themes or easily create your own cursors. It integrates into the standard Mouse interface of Windows and is easy to turn on and off as you need. Works both on XP and Windows Vista.
KeyLemon (Win XP Only)
This program automatically locks/unlocks your computer by looking at your face. It is light on system resources and takes seconds to configure. It’s not something that will make your computer a lot more secure but works quite well if you want to impress women
Real Desktop (XP / Vista)
You have probably heard about Bumtop - application that transforms your desktop to a 3D play ground. It makes your icons look and act like real objects that you can touch and move as on a real desk. The only problem with it: it’s been in closed alpha for ages. However, there is another program that delivers pretty much the same interface and you can get it right now. This program is called Real Desktop and it even comes with a free version. Although a freeware version offers no styling options it is still enough to get a feel of it. Check out my sreenshot and a video demo that I found on Youtube.
these makes me wish, i could stay at home, and play with my own computer the entire day :D
