When people talk, they often gesture with their hands in order to explain a task or a concept. These hand gestures not only help to communicate a message to the listener, but also reflect the thoughts of the person who is gesturing.

But in order to become a genuine thought leader, then you'll first need to master all the right hand gestures. And that's where this handy instructional website comes in. The Glossary of Gestures for Critical Discussion is a virtual manual created by Alice May Williams and Jasmine Johnson which demonstrates nine powerful gestures and includes instructions on how to use them effectively.

The gestures have also been immortalized in a poster series for Public Assembly and now exist as a range of handy goods, including tea towels, coasters, mugs, and, most impressively, an animated lenticular ruler which can all be found here. It would make a perfect gift for that faux-intellectual you have in your social circle.
