Is Martin okay?

…I figure he must be someone I was chatting to in the Cornerhouse or somesuch. A few more clicks and it became apparent that he is some crazy multimedia artist type and happens to be involved in a thing called the Velocity Festival based at Folly Pictures in Lancaster (where I used to hang out) and has been taking photographs of Morecambe Bay in some kind of interactive GPS-tracked SMS-influenced way and that this would all be visible from the “Map room” on platform 3 of Lancaster Station. His facebook status is currently “Martin is okay” a missive he has been repeating periodically for the last few weeks. What if Martin is not okay? What happens then? What if he’s got a cold or something? Anyway I still am not quite sure who he is…
