Tool for Translating VB.NET <-> C#

A blog entry led me to this, an awesome C# <-> VB.NET code translation tool. Man, this is excellent stuff! It also colorizes the translated code a.k.a syntax highlights. The nice part is that it uses Ajax for posting and retrieving result. This guy also did some other nice tools like for making DB diagrams, UMLs, and a CodeColorizer. I've tried to make a colorizer/syntax hightlighter myself about a year ago. Abandoned it after several tries. I actually gone half-way, but the HTML produced was quite long. Don't remember why I stopped. I got a lot of work at that time I guess.
