Hi Jonah,

> That's great, Michael. Can you also make a version to grab an image of the Z Buffer? :)

Unfortunately that is a bit more difficult. I'm not sure that you would want the actual Z-Buffer anyway, since it is non-linear. My guess is that you would want a depth image that had a linear mapping between depth and color?
