How The Frack do I do the Turing Google Doodle? I don't know. And you can't ask Turing because he killed himself because assholes can't seem to let people live their lives as they see fit.
My friend Jon did figured it out:
"Match the digits on the tape to those in the upper-right. Instruction execution moves to the right. Big arrows move the tape, 1s and 0s change the digit, small arrows with boxes are IF conditions that test the state of a digit, and arced arrows jump back to a different instruction. Match all digits, and you add a letter to "Google." Fill the entire word, and you get a prize!"
