> creating orbital magma cannons that can target any part of the world

Mind giving the gist on how that's done?

Isn't Little Big Planet Turing complete?

Create a floor filled with hatches on a very high z level that covers your embark. Link all hatches to levers in a control room of doom somewhere. Pump magma up from the magma sea. Laugh manically when you flood the surface with magma :) (and destroy your FPS...)

Not sure about LBP as I haven't played it. I was hoping wikipedia would have a list of Turing-complete games but I can't find one.

Not a wikipedia page, but LBP is included in this list of accidentally Turing-complete things.

Magic the Gathering? You made my day. Of course, even rocks can be Turing-complete :) http://xkcd.com/505/

Rocks don't have their own rules on how to "execute." Calling the rocks Turing-complete is like pointing to a Turing machine's tape and saying it's the tape that's Turing-complete :-P

Good point, well made.
