Here are some of my recent inspirations:
This is pretty cool because it is really just a scene that has clickable hot spots with audio, visual or text embedded into it. It really personalizes the experience in a fun way.
This website features an image of a rainforest with a scroll over-able grid. On the grid you have the ability to click on squares which represent acres that you can pay to protect.The interface is really clean and nice, and its informative at the same time that it is getting you to take action.
3. Urban Plough
Urban Plough is a site that uses google map images of a farm and allows you to scroll through and look at the changes in the environment over the years. Additionally there is information that pops up about the land based on the year and then embedded within the images are markers talking about specific projects happening in that location.
