And even Window Blinds will be pretty limited in what it can do. Aero is a major reworking of a lot of the Windows internals, and XP will never be able to duplicate those abilities. So, you have four options that I can think of.
1: Upgrade to Vista
2: Get a Mac (virtually every graphical change in Vista was copied from OS X... Poorly)
3: Use Linux (if you enable the Composite features)
4: Abandon the idea completely
Take your pick.
I've been trying to make windows XP look like vista. Does anyone know of a FREE program that can make the tool bars and stuff transparent like the vista aero glass effect. So far all I've found is Windows Blinds which I'd have to pay for and programs which turn the whole window transparent.
