One of the things we talked about in our Innovation Briefing on RIA was Sidebar Gadgets. In that discussion, I explained some of the reasons why you would want to create a Sidebar Gadget, but now I have another reason: Microsoft Canada has created a contest for building Sidebar Gadgets and one of the prizes is an XBOX 360 Pro! The other prizes are a 40" Samsung Widescreen LCD HD TV and a Dell UltraSharp 24-inch Flat Panel LCD Monitor.
All the rules and information can be found here.
Enjoy and good luck!
