From BruCON 2017
Lightning Talks are 4-minute talks by various people combined in a set of 10 talks in one hour. You can present a strange idea, your nifty program, a cool project, some hardware you like - or whatever.
These talks can definitely be used to talk about the booth you are maintaining or the workshop you will be giving.
