The Public Interest Projects web site is a semi-custom theme. It started with a pre-made base theme that’s been so heavily customized not much is left. The PIP site was also a challenge in that the project suffered from regular scope creep.
One of the items added was a feature with Google Maps API. The client wanted to show where they were supporting projects, but not give out the actual addresses. For this project we created a database and then tied it to the Google Maps API to generate location dots. With a little math, each group was gridded to create a matrix affect. When you zoom in you’ll see a grid centered on the area. This has turned out to work pretty well.
