This also makes me think about how much junk I have on my desk. Maybe it's time to make some strategic decisions and cut down on stuff I haven't looked at it too long.
I did this pretty quickly in GIMP. I took the photo, duplicated the original and made the copied layer monochrome. Then, I applied a white layer mask and used the free select tool to get nice, crisp lines. I then filled those spaces with black to erase the mask and let the colors show through.
