The Germs logo and PCLinuxOS logo are closer than the srcphp logo and The Germs logo. But given that they are all variations of blue circles, there have to be thousands of companies/organizations (At least) with a variation of the blue circle, chopped or whole.

[Edit] I did a quick search. They are all stolen from Blue Circle Industries. See for yourself:

But really, probably not. Someone else must have had it before.

Really, the logo should've been implemented in Logo.
