TIMTOPL - There is more than one Perl logo (BAOTATM - But All Of Them Are Trade Marked):
My favorite Perl logo, by far, is the onion. When it appeared, I found it the perfect logo: simple, recognizable, easy to include and modify. It was quickly adopted by the community (I remember seeing T-shirts with the logo very early on).
In his 2nd state of the Onion, Larry said:
If you cut an onion, it looks like this. If we take this to be a picture of the world of Perl, then I must be that little bit of onion inside. Around me are some of the early adopters of Perl, who are now revered as heroes of the revolution. As more people have joined the movement, new layers have been added.
When I saw the onion logo, this image sprung to my mind. Maybe the Onion is the symbol of the Perl Community, rather than of Perl itself.
