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.
Over at the I'm Just Creative Blog Graham posted about exploring logo designs with Mathematica. Since I can't afford the £2000 pricetag, I dismissed this as outside the realm of mere mortals and amateurs.
Then I remembered I have had some experience with Processing:
...an open source programming language and environment for people who want to create images, animations, and interactions.
This is a follow up video to meet the Gimp 158 http://meetthegimp.org/episode-158-three-kinds-of-particles/
"How to create a random pattern of particles that follow a gradient in density."
This is the same a Saulegoode's suggestion to use the dissolve layer mode.
