Pecha Kucha presentations

[Pablito]

Hello,
So what about these new formats of presentations: Pecha Kucha and Elevator Pitch?
Have you heard of it?
Did you present in these brief styles? Share your experience.
What is your opinion?

I've prepared some templates for Paecha Kucha presentation.
The rules of Pecha Kucha are simple - presentation contains exactly 20 slides with automatically transitions after 20 seconds, so in total we have 20*20=400 sec (6 min 40 sec) per presentation.
I played with visual representation of 20 seconds slide's "lifetime".
One example I attached to the message, other you can find on my site in MathArt section.
