Symbolic DNA Sequencing

Imagine there is a device that can scan across an image of DNA, like a photocopier, and work out how much black there is in each line of the image. What you end up with is a squashed down representation of the DNA, showing how much stuff there is at a particular place in the DNA.
If our line detector were sensitive enough, then we would be able to distinguish the four different bases just on this profile alone. A and G look similar, as do C and T. Similar, but a well-trained eye would be able to tell the difference.
