I'm with foinavon. Have completed and think I have the endgame in that I have joined some omission points and got something that looks relevant, but haven't the faintest idea what p and q are or what on earth is going on. Enjoyed it though.
Thankful that it was relatively quick as I had three listeners on the go at 4.30 on Friday. Fortunately finished kea's excellent effort on friday night so now have a few days to try and make some more progress with my half-completed oxymoron from 2 weeks ago...
