I want to play on Saturn!
In case you missed it, Nikhil has posted a screenshot of the new Web Matrix. Looks pretty cool, but I'm wondering about the theming comment. Now, is web matrix simply taking advantage of the built in windows theme, or are they doing something magical to give their app a new theme.
My guess is the old watercolor theme from some of the Whistler builds makes a comeback in Longhorn. If you are curious, you can download a hacked together theme from TweakXP. Note, the copy from TweakXP isn't for the weak of heart. It involves replacing your uxtheme.dll in recover mode with a version hacked out to enable custom themes...
I wouldn't call it magic, but if you look through the code using Reflector then you will notice that they have an entire managed UI framework (codename Saturn) with all kinds of bells and whistles. There are all kinds of goodies like the syntax editing control, enhanced versions of nearly every single Windows.Forms control, XP style menus and toolbars, etc, etc. Basically, Web Matrix is their playground for cool stuff and we are not allowed to play. :-( It's very obvious that they have spent a ton of time building this framework out. It would be awesome if we could play too!
