Thanks to everyone who responded. There were six genuine voters and two virtual voters. Analysing the responses was not as straightforward as I had expected.
Kate voted for option 3. Kate's cat also voted for option 3 but I suspect this was just Kate's way of trying to wangle some extra representation and so I'm accepting only the one vote (sorry Kate's cat).
Cosmic Tink Tank voted for option 3 and included some interesting suggestions to enliven the proceedings. I won't be using the suggestions but, hey, what a creative mind.
Mille Vache voted for option 2, which I would have been delighted to run with but unfortunately Mille rendered option 2 redundant by publishing the recipe in advance of project selection and execution. Never mind - it was a good service rendered by Mille and I trust everyone will try the recipe (I certainly will).
Angie voted for option 2 but see Mille Vache above. Sorry Angie. At least you've got the recipe now.
Andrew voted for option 2. Yep, that's right. Sorry Andrew. Blame Mille Vache. Enjoy the honeycomb!
Su voted for option 1. I am counting this vote as valid even though I know for a fact that Su is voting that way only to try to put me on the spot. You don't believe I can do this number theory stuff, do you Su? I have only one thing to say: Tom Westerdale, Birkbeck College. He taught me everything I know about number theory, set theory, logic and computability. Although I'm a wee bit rusty, I've still got my notes...
Anonymous voted for option 1 but then disqualified himself/herself by voting twice for option 1. A bit harsh maybe but Anonymous could be anyone - perhaps even Su trying to inflate her representation. Anonymous did almost redeem himself/herself by suggesting that option 3 would be more fun but, in all fairness, if I'm invalidating this person's vote for option 1 then I must do the same for option 3.
So there we have it:
Option 1: one valid vote (Su).
Option 2: three valid votes (Mille Vache, Angie, Andrew) but option rendered redundant by early disclosure.
Option 3: two valid votes (Kate, Cosmic Tink Tank).
A clear win for option 3. I kind of thought it would go that way.
When is it going to happen? Well, I had planned on doing the deed later today but a friend of mine offered the use of his professional quality video camera in place of my humble mobile phone video capture facility. I must admit I couldn't resist the opportunity to capture some high-speed vid and render it in slow-mo for your delectation.
Do not try this at home. See you in March!
