Alan Turing was an English Computer Scientist who invented Turning Machine, a device that manipulates symbols on a strip of tape according to a table of rules.

On 23rd June, 2012 Google showed an excellent interactive animated Doodle representing the simulation of some kind of Turning Machine.

Similar to Turing Machine, the Doodle is showing Tape Strip with various symbols like 0, 1 and Blank.

And, it is having some kind of logic (e.g "If the tape symbol value is "blank" set the value as "1″ or the value as "0″). And the user can change these logic so that the values match with the code (e.g 01011) displayed at the top right corner.

Once the user is setting the logic to match with the expected value, he can click the Green arrow button to start the verifying process. If all the symbols are matching, then it will be showing the "=" symbol with Green color or it will be showing "Not Equal' in Red color. And, initially the Letters in the Word "Google" will be greyed out. Once the matching happens, the letters will be getting displayed in usual color one by one.

The code for the Word "Google" is 01011 00011 00011 01011 01001 10000. It looks like some kind of Binary coding . (It is the ITA2 (International Telegraph Alphabet No. 2) code developed based on Baudot -- Murray code.)
