UPDATE: Thanks to sixfoottallrabbit & Maqrkk from the SpoilerTV forums for passing this second image along. Maqrkk notes "for this to match I had to rotate the Dharma symbol 90 degrees clockwise.":
Check out the process sixfoottallrabbit used to do this here: One, Two, Three & Four (a plot of what all the dots from the logo would look like.)
