One of my clients was having their annual kickoff meeting at the Westfields Marriott in Chantilly, VA. The meeting was unique in that they had about a half dozen of their younger consultants give five minute presentations and their sideshow had to be 20 slides with each slide showing on the screen for 15 seconds. This ensured that every presentation was sharp, focused, and to the point. It really seemed to work well, the audience was very attentive and seemed to enjoy the format.
Since we had most of the employees of the consulting firm at the meeting, the marketing director had a great idea, setup a studio outside the meeting room in the lobby of the Westfields Marriott and allow people to get new headshots done for their Linkedin profile and for other internal uses. Many of the "selfies" that employees use for their Linkedin profile tend to be a bit crude and not that professional looking. I photographed 90 employees in less than 60 minutes while everyone was enjoying food and refreshments after the meeting.
