After playing with the Mercedes Logo I figured I'd follow up with another Processing application to try and duplicate what Christopher Carlson did in Mathematica to allow dynamic interaction with a logo created by Franco Grignani special edition of the magazine Advertising in Italy.
I parametrized a few more options, set some up by guess and by golly, and added the "hidden" feature of dragging your mouse to move the center of the innermost disc...the "focal point" of the logo.
