Creative Ideas for Presentation on the 1920s

I'm in a group of four people that needs to present a 20-minute presentation on the 1920s. We need to cover all relevant events and areas (ie economics, entertainment, politics, etc). While giving an informative presentation is easy, the information only counts as 1/3 of the grade! The other 66% is made up of the creativity and entertainment factor.

Ideas that have been used in the past include a news broadcast (acted in room), radio broadcast, skits, food from decade, etc. I can incorporate some of these ideas into my presentation, but I'd rather not just copy them completely! If you have any ideas for a really creative and entertaining way to present the information, please share!

.... is a 'life-sized' board game.

We used four sheets of polythene 2 metres by 10 metres and marked them off with one metre squares: the people walked around the board using themselves as the counters.

We had the full whack of "recession: four squares back" and all that kind of thing as well as things like a large water pistol on a square and the instruction "Shoot the team behind" when there was small war... use your imagination.
