Agree with a lot of ideas here.
I've been having exactly the same ideas as johnno.
The public having the desicion of who goes in, I mentioned this last week. Whether it be like the Pop Idol format or not could be thought over.
Instead of replacing "walkers" with new people, have a task that enables housemates to nominate a previously evicted housemate back in.
I think something like GeeBoy's idea would be great.
Have a task, in which a winner can watch E4 for a day, with access to whatever luxuries he/she wants.
But the thing is, that this is a secret that can not be mentioned to anyone else. if it is, they're OUT. Full stop.
A Winter version of BB.
possibilities here are endless.
People could have all that pantomime stuf iff they wanted, party tasks, christmas trees, .
Resricted to the house would mean they would get closer, as friends OR enemies which would create some tension.
Hot-tub in the garden with snow all around would look good at night.
Mistletoe for the ones who want to get close.
I mean these are things just from the top of my head, I'm sure that there's loads of possibilities.
Not forgetting a final night which could look spectacular if they got the design right.
The prize money £1000 000, say, would be the ultimate Christmas present.
I know it might seem unlikely, but I think it could work really well.
