It's been a while since I've been this giddy in one day. 

But I can't help it.  I don't even feel like working on any of the stuff that I'm supposed to be working on. 

A video posted at channel9 demonstrates what Microsoft has been craftily hiding with "Sparkle". 

Wow.

It's really hard to describe my internal feeling at the moment; it's a childish giddy-ness.  I started jumping around, trying to tell people about how awesome this really is and the implications it has for software development.  No longer are we constrained to plain-Jane UIs!

In addition, it's also incredibly impressive that they've basically integrated a 2D design environment, a 3D design environment, and animation tool, and VisualStudio in one.  It's quite a task to surmount and I'm really, really juiced about getting my hand on this.
