WindowBlinds is a commercial application that packages the same kind of effects that can be done manually by importing themes, but it does it in a collection of products that don't require you to patch anything.
I have been a user of WB for years, and participated in the beta testing of the most recent version -- and have decided to NOT use it anymore because of problems I discovered during the beta testing that would crash my PC, lack of upgrade of legacy blinds that I really liked with XP, and the fact that I can get much the same effect on Win7 (especially my non-Aero capable Tablet PC) by using themes obtained from DeviantArt.
You should visit the StarDock site and see what they offer. You will have to decide whether or not it is worth the money -- to you.
