Pretty interesting... it really makes you ponder how many things in our world can be refitted and sequenced into codes.

Any set of six things can make a turing machine. You just need "instructions" for each of the primitives -- right, left, print, erase, scan, halt

Any set of three things can make a Turing machine as well - you just need AND, OR, and NOT

CAR, CDR, CONS suffice as well
