Alan Turing, a man you've probably never heard of and you probably couldn't live without his work, would have celebrated his 100th birthday tomorrow. Mr. Turing was the man who basically invented modern computing. He was also significantly important during World War Two due to his work in cryptography and code breaking.
Now, one of his inventions has been rendered in Lego form as a cerebration of his brithday, which, for inventors, is like an actor being parodied on The Simpsons. It's a sign that you have really made it. The machine is really simple and the heart of the machine is a Lego Mindstorms NXT set, but the soul is Alan Turing's genius.
The use of Legos demonstrates just how simple his machine was:
It's very simplr, but describes the fundamental capabilities of practically all computers in use today. This means that if something can be done on a computer, it can also be done on a Turing machine. This makes it a great model for scientists to use to discover the limits of computers (e.g. complexity theory) and also to show to a broad audience how a computer fundamentally operates.
The Lego model is on display at Asterdam's Centrum Wiskunde & Informatica's Turings Erfenis exhibit. The only difference in the Lego version is the lack of an infinite tape. The Lego Turing Machine only has 32 positions. If you aren't in Amsterdam and are unable to see it, you can check out the video in the source link.
