I've just been passed a couple of links to the code-swarm system. It's a method a visualising the development process of a software project – and it's pretty amazing looking! What this system does is use the commit process (aka check-in) of software development to track the additions to a software project. This is where a developer takes a copy from the central control one of the source files and adds to it, then places it back into the repository.

There is a considerable amount of internal competition in biology. By this I mean that internal to an organism, it can compete within its self to produce the best 'goods'. So for example some plants will abort the growth of fruit where it does not have enough seeds. One could see this as a form of internal-competition between possible fruits so that only the fittest has the resources to grow it to full term, is used.
