The 'If It Was My Home' website uses oil spill visualizations to demonstrate the seriousness and severity of the BP disaster. The website allows you to pick your location and from there, transports the big black spill onto the location you pick.
When I tried out the oil spill visualization, I was shocked at how large the area was. Natural disasters like this are always tragic and shocking, but if you live in a removed area, it's hard to grasp their effects. IfItWasMyHome.com uses oil spill visualizations to bring catastrophic events like this closer to home.
