Download WinFlip 3D, to switch XP windows in Flip 3D mode
WinFlip is a Flip 3D function for Windows XP. It provides an alternate window-switcher to the standard Windows Alt-Tab. Winflip displays all open windows in a 3D stack, which the user can flick through and select using either keyboard or mouse.
I must say that the usual XP Alt-Tab is the fastest and most convenient way to do your job quickly, but WinFlip-like 3d switch is fun – and it works great. The good news is that WinFlip does not replace the standard Alt-Tab switch, it just provides a new option (WinKey-Tab by default), so that you can have both ways available to use at will. Enjoy!
