Dr. Eamonn Keogh at UC Riverside developed a method to visualize and compare the similarity of DNA sequences of different species, like human and chimp:
You often hear that Human DNA and Chimp DNA are 96% the same, but what does that really mean? This video shows a way to actually visualize the similarity (Note, it is two minute long, you really need to see it to the end).
