This is for a great real estate team based in Ottawa has a few really unique things going on. With a customized Timeline feature (with some interesting math used to place the items on a line based on their year) and an advanced Google Map that plots neighbourhoods and links them to their individual page.
The Google map feature was really fun to work on, taking advantage of Googles kml resource to connect to a prebuilt map of the neighbourhoods and matching it up with a Custom Post Type. Look for a tutorial on this in the future.
