I'm starting to look into the ASP.NET MVC Framework and needed to download the CTP just now which is not all that interesting. What is interesting though is the fact that I was greeting with a dialog asking me whether I wanted to try the new Silverlight version of the MS Download site. Naturally I couldn't resist :)
Check out the MS Download Center beta done in Silverlight.
