As Jackson & Kent were tweet-spammed about "Le Web 09", they got an hypnotic idea :

How does it work ?

The flash application get, at irregular intervals, new tweets containing "#leweb" and screen up a Jackson or a Kent, that you can click to see the tweet.
In the center, you can see the number of tweets since you started the application.

Fowarding

This kind of application is not new, but keep in mind that there is only 2200 attendees at the event.
Since there is right now 30 tweets per minute, attendees will have in 8 hours sent 14 400 tweets, wich is about 6.5 tweets per head !

(Jackson & Kent agree, some other people are talking about it too :))
