Here is a list of the best ones I know.
Transparent Windows 2.0
http://www.tucows.com/preview/347392
This is the best one I've used by far. Instead of an icon or things like that, there is a slider bar beside the minimise/maximise and close buttons. This is definitely my favourite one by far : D Also, on the start menu you can right click the program and select a transparency level.
Actual Transparent Window

I've used this briefly, but I hate shareware and trial so it was gone in a Flash. If Stickid wants to add a review in a post I'll be happy to add it.
Froost

This is ugly and slightly awkward to use, due to the fact that it can't be brought up from the systray icon. It's still good because it's only about 56kb! I carry it on my flashdrive along with Pivot.[url]
