My friend and colleague Brian Peek has been developing some awesome and fun applications for a while. As a contributing author to MSDN's Coding 4 Fun Bran has been creating some cool applications that you should really check out at his site at www.brianpeek.com.
Not his latest, but certainly one of his most famous, achievement is his Wiimote .NET Library and the uses that he is putting it to. Brian got the attention of Newsweek magazine for the Wiimote .NET library that he authored. They interviewed him and the article can be found on line at http://www.newsweek.com/id/136381. The print article should be in the May 19th issue of the International Edition of Newsweek.
