Someone has submitted a working turing machine to Lego Ideas and I'm loosing my mind over how cool it is: https://ideas.lego.com/projects/10a3239f-4562-4d23-ba8e-f4fc94eef5c7 #lego
Turing Machine – Working Lego Computer

What is a Turing machine?It's an abstract model of an algorithmic machine. Although it was not designed to be implemented in real life, some people ...

@chorrell that is amazing. Looks like a nice fiddly build
@chorrell
omg... that's mind blowing 🤯
@chorrell The tape is a bit shorter than the spec says. 😌
@chorrell this is seriously cool. And lead me down the path of re-reading about Turing Machines which I've not brushed up on in years 😅

@chorrell so ... a computer that still works when we blow ourselves back to the stone age? 🤔

(Except, we'll have to make it out of trees and power it with donkeys… )

@chorrell amazing work, thanks for sharing!
@chorrell Impressive, thanks for sharing this! Of course a Turing Machine would technically need an infinite "tape" but I guess the laws of physics, economics, and the Lego Ideas platform (3000 bricks max, apparently) make this tricky in practice :-) #TuringMachine #Lego
@chorrell Cool, yes, but with limited fun potential after the first “haha, it is indeed a Turing machine” imo
@chorrell But can it run Doom? ;)
@chorrell this is reminiscent of Charles Babbage's work, some fascinating parallels and differences. Best source on Babbage for anyone interested is the Sidney Padua book (which is entertaining and whacky but also full of great detail).
