Windows Vista flare animation

I think this is cooler by itself than it is in Windows Vista. As Jenny Lam of Microsoft Design described,

It’s not so much a new theme as a new brand element for Windows. We were feeling a little creatively trapped when it came to the Windows identity especially with branding the user experience (in UI). We know we didn’t want to slap the Windows flag logo everywhere (disparaging to the flag!), so we created this new little sweet, light gesture animation in the UI. I have to admit, there’s still some little treatment-like work I’d like to do to it.
