Tried the Map mode of the EDX for the first time last night. In the center window you can see an image of the sample (U Ore) and the surrounding images are heat maps of different elements that are found in that image. the more towards the red end of the spectrum, the more of that element was found. This was a "quick" 256x256 scan at 15ms per pixel dwell time. It took 15 minutes. Looks like it is a very time consuming process but still pretty neat.
