It's a penguin.
I have a warped view of the world, but there are a lot of parallels in hotrodding and Linux. Richard Stallman started the GNU project because of all the restrictions on software, back in the early '80s. He needed a printer driver and all of them were closed source with terms he just couldn't agree to. Linus Torvalds started writing Linux because none of the operating systems he could get for his computer in '91 were good enough. Now anybody can get the parts or 'kits' or complete systems and customize them any way imaginable.
Hotrodding began pretty much as every man for himself and ended up changing the whole automobile industry. Things can still be done just as you did them with your rat on a shoestring or a person can go into a dealership and buy a car that resembles a hotrod. There is a whole slew of options in between. Same thing happened with GNU/Linux.
There is also a parallel in the fight with regulations.
