I just finished up my sample for the 2.0 version of the Post Processor (see first post on this blog) for XNA2.
The sample was built in XNA Game Studio 2.0 on Visual Studio 2005 Pro, and should compile fine in that. To use it just follow the instructions in Usage.txt, which explains how to use the program and also that there are more than enough comments in the code to understand its workings.
If you have any questions, you can use the contact link at the top right, and get me via that, or you can contact me via the forums at www.thehazymind.com/smf, probably best via PM there though, since its not my board. Of course you can also leave comments here. :)

PostProc2Sample.zip [28kb] (Requires XNA 2.0 and either VS2005 or C# Express Edition 2005 installed, with XNA GSE 2.0 installed over that. - The archive only contains source code to minimize filesize, if you need a binary I will upload that.)
