A while ago PO stated he had written a Turing Machine that did what one of the impossibility Lemmas said was (you guessed it) impossible. So we asked to see it since it would be trivial to code up a TM interpreter and see how his puppy played. That would satisfy Stefan's quest I think. However, this PO announcement like all of the PO claims was bogus. In fact after everybody said "show it to me" and he couldn't, he started starting maybe five or more new threads a day trying to bury his phony bologna. Every few days someone asks to see the TM definition and PO dances all around and doesn't admit his claim was premature. The situation would be rather humorous if we all weren't witnessing a human life totally wasted -- Jeff Barnett
