He also installed Finux, a free UNIX operating system created by Finns, almost as a way of proclaiming to the rest of the world "this is how weird we are," and distributed throughout the world on the Net. Of course Finux was fantastically powerful and flexible and enabled you, among other things, to control the machine’s video circuitry to the Nth degree and choose many different scanning frequencies and pixel clocks, if you were into that kind of thing. Pekka most definitely was into it, and so like a lot of Finux maniacs he set his machine up so that it could display, if he chose, a whole lot of tiny little pixels (which displayed a lot of information but was hard on the eyes) or, alternatively, fewer and larger pixels (which he tended to use after he had been hacking for twenty-four hours straight and lost ocular muscle tone), or various settings in-between. Every time he changed from one setting to another, the monitor screen would go black for a second and there would be an audible clunk from inside of it as the resonating crystals inside locked in on a different range of frequencies.
