James Newman, a software engineer in the UK, spent 3 years and the equivalent of $51,000 constructing a computer that fills an entire room of his house. It plays Tetris.
That's it. Just Tetris.
That shouldn't be surprising. Although Newman's computer is physically large, it's technologically primitive. It's slower and has less memory that most desktop computers. It's a simple processor that he built piece-by-piece. With it, Newman hopes to educate people about how computers work The Huffington Post reports:
Newman is now planning on holding open days at his house for people to see the machine.
“In the longer term I would like to put it in a museum or go on a road tour to show people,” he said. “I want to show people how computers works and get children interested in electronics.”
