Lightning Talks

From 35C3 Wiki

Lightning Talks are short lectures (almost) any congress participant may give!

Bring your infectious enthusiasm to an audience with a short attention span! Discuss a program, system or technique! Pitch your projects and ideas or try to rally a crew of people to your party or assembly! Whatever you bring, make it quick! To get an idea what Lightning Talks are about and how they work, look at last year's sessions.


The Lightning Talks are full! Registration is closed, as all the timeslots in the three sessions are full.

There is an additional, self-organized session for all the speakers who could not get a talk in the Saal Borg sessions. See [1] for details, schedule and contact info.

If you have any questions, please send a mail to the Lightning Talk team. We speak English and German.


Please see for a schedule in various formats like iCal, JSON, XML.

Lightning talk sessions are offered on Day 2, Day 3 and Day 4 of the congress.

Each session starts at 11:30 and ends at 13:50, with a 15 minute break from 12:35 to 12:50.

All sessions take place in Saal Borg. Resistance is futile.

In the unlikely case that something bad happens to the wiki or this page, follow @C3_LightningTLK on twitter for announcements.
