Nicholas Negroponte had a laboratory with a strange title; it was called the Architecture Machine. And... I think maybe this was because Nicholas’s... PhD thesis was based on a really remarkably humorous and interesting idea that... I don't know if I can explain it. It was a box that had a lot of guinea pigs and a lot of little wooden blocks. And in the course of their activities, the guinea pigs would run into the blocks and push them around and... Nicholas had some system, which would record – maybe just photographs – where the blocks were each day. And... he arranged some kind of plotting machine, which would... I think we may have to erase all this, but he had this machine that would observe that a block had been moved and reach down and move it back. And then, he would record whether the guinea pigs paid any attention to this or appeared to have any intentions about where they wanted the block to be. But I... I give up. I can’t remember the purpose, but anyway, that was called the Architecture Machine at first. And then, he had more students and Nicholas was incredibly productive at... at the beginning of computer science, of... thinking of things that no one else imagined computers doing.
