I started from an idea which in fact turned out not to be very original. I thought, why not go for aperture blades (or whatever you call them in english)? But make them colored like the hue wheel. Hmm, turns out I’ve seen that in Picasa and my brain fooled me into thinking I actually came up with it. sigh So to save the day, I simplified it into a bunch of polaroid snaps forming the aperture blades. The font is Arial Rounded Bold, just like mono itself.
Not sure if this is distinct enough. In the end, perhaps the man himself could offer a sketch, eh?
