I've been a strong supporter of Sketch, InVision and other new tools. To raise awareness within the company and get more workmates to use them too, I've run a 1.30h seminar for 40 team members of Creative and UX at razorfish NYC.
I designed 5 teaser posters and few dozens of slides. I presented using Sketch and InVision itself, quickly demonstrating each feature by manipulating the layers of each slide.
