Turing Machine is a theoretical computer. As far as I know, an actual Turing Machine does not exist, only machines that are equivalent to it (in the mathematical sense). I guess it would be possible to build one, but it would be highly inefficient. It's called a Turing Machine after Alan Turing, who thought it up while doing cryptography work for Britain in WWII.

Neal Stephenson's "Cryptonomicon" points this out as well. I'm not saying that what it says is entirely true (though I believe the basics behind the Turing machine as explained in Cryptonomicon are), but it is still a good - no, make that excellent read.

but as for your 1-color lavalamp NA, that's really relaxing.
