With WPF, Microsoft provided developers with a way to build very rich user interfaces. I've been waiting to see how developers would use these new tools to rock our world. One of the first apps I've seen that does a pretty good job is Ript. Ript is a simple, but addictive application from the good people at Oxygen that lets you drag almost anything into it and create and share scrapbook-type pages. Check it out at http://www.ript.com.
