Solar Shadows

Here is the solar shadow model that I created using Google SketchUp. This software allows you to actually set your place in the world by using Google Earth. all very cool.

When you watch the video you will see the shadows going across the house (takes a few seconds to start, ok more like 10 seconds to start) The first time the shadow go across the house I have the date set to Jan 15th second time Feb etc. Each time the shadow goes across the house this represents a single day. Just for reference the house being studied is the one with the shadows on it.
