I am doing my first super short talk this year at the ESA. This is the first time for the ESA trying the model, and the presentations in these sessions are called ‘ignite’ talks. It is 5 minutes long, 20 slides auto-programmed to advance, and the purpose is to promote discussion.
Here is the link to the session I am participating in: http://eco.confex.com/eco/2013/webprogrampreliminary/Session9041.html
It will probably look something more like this though.
