Just finished with a client’s website www.wildwoodcampsites.com, I am pretty happy with it and so are they.
Few things that where fun was implementing a "Get Directions," Map with Microsoft Virtual Earth and a Silverlight picture viewer. I have worked with the Google maps api in the past it wasn't bad, but I hate the registration it makes it a pain to move and reuse. I found virtual Earth API far superior with great examples. I was able to get something cool up and working with little Java Script experience. The picture viewer I did not code from scratch, dnntemplet.com was offering it for free as a Beta version; although it didn't work I was able to fix it by digging around in the source code. I am really excited to see what the web will look like coming up with Flex.org and Silverlight 2.0
