How much notice do you reckon people would need to have a routine ready on the day?

This seems an interesting way to do something different with the Caramelldansen concept.

I like this very much! One way I could see this working, if you have a nice open space:

1. Pick the anime-related dancing craze of the day (I think HHY and CD have probably overstayed their welcome, but others may differ - there's a good chance something new will crop up by the time SMASH 2011 comes around)
2. Put the music on loop
3. Have participants start dancing
4. Get judges to walk through the crowd of dancers and tap the least impressive ones on the shoulder - they're out and have to leave the floor (safely, of course)
5. Last dancer standing wins!

This keeps it relatively quick - you may not even need to loop the song depending on the number of entrants and how fast the judges eliminate people - and high energy, it scales well, and if you finish with two or three people that the judges can't choose between, have some kind of tie-breaker.

Alternatively, similar set-up but just loop Caramelldansen and get people to dance until they drop. It's an old format (back in the 20s I think it was they used to have ballroom dancing marathons, that lasted several hours and I think in some cases over a day), but probably poses a huge OH&S risk since I assume SMASH doesn't want people fainting from over-exertion just because they wanted to win a competition.

@LordSabbo A month, maybe two months? I'm not really sure. Then again, I'm one of those people who take forever to learn dance steps.

@ConMan I humbly suggest Danjo, Lucky Star, Kero 9 Destiny, Cirno's Perfect Math Class, and Bad Apple!! as anime-related dance crazes. Of course, a few of them are ridiculously choreographed and need time to learn. (Especially Bad Apple!!) I could really see the first suggestion working as a competition. The second one, as you said, poses a bit too much of an OH&S problem.

Now for the obvious problem, is there any room at the convention center that's big enough as a dance floor?

@acq128 Sure, why not? However, while it's always nice to see a fan favourite, I think there needs to be a bit more variety in our choice of anime dances.
