Thank you! Yep, that was me . . . long hair and rather strange axes.
Was always onto something of a loser (trying to convince a 90% non-climbing audience that a new type of ice tool is the best thing since sliced bread never was going to be a winner), but learnt absolutely oodles of stuff and if I ever have to do something like this with serious intent I'll have far more clue as to how to go about it . . . quite a lot of what I was doing worked, but there are some things I'd definitely want to do differently.
Now feeling something of a sense of achievement at having survived it all.
