In November of 2018, France erupted with a series of unexpected, disruptive, and seemingly spontaneous marches and riots.
It was more a series of flash mobs driven by social media than the typically French political uprising led by a cadre of charismatic leaders and ideologues.
The activists wore bright yellow reflective vests, the kind often worn by both construction and emergency workers.
There was no visible public relations firm behind this brilliant visual branding. It was ideal for a digital, viral world fixated on smartphones and laptop computers.
