Now that Vista has RTM'd I thought I should get some of my demos cleaned up and out into the world.
I did a demo of this Gadget at Dev Connections in Las Vegas 10 days ago.
Dr. Neil's Route Finder uses Virtual Earth to find a route using the VE API's.
The Gadget lets you display the route in flyout windows on the desktop or on a SideShow display if you have one available.
Update: changed SideBar to Sidebar to keep Microsoft marketing and Mr. Moth happy ;)
Woops! The link on the page went to the SideShow test gadget - fixed now.
