Glass 2k is a little freeware application for Windows 2000 and Xp which makes it easy to add a transparency effect to any window on your system. A great feature of Glass 2k is that it is able to remember the transparency settings that you set in a previous session. The default keyboard shortcut to add transparency is CTRL + SHIFT + a key between 1 and 0 with 1 being transparent and 0 not.
