Put Alan Turing on the £10 note!
Peter Flint sez, "Alan Turing, computer pioneer and geek hero, is generally credited with helping, via his work at the top-secret Bletchley Park code-breaking centre, to shorten World War 2 by anything up to two years. He tragicaly took his own life after his (then-illegal) homosexuality came to light. One way to commemorate his work and to make his legacy more widely understood waould be to include his picture on the next £10 note. Sign the petition and help this to happen!" The richest person in Britain would be Turing-complete.
