For Wikidata Workshop 2019 in Ulm each participant recieved it's own individual badge. The colors and pattern encoded information collected by a small survey beforehand. It contained questions like "What's your favorite baverage? Tea, Cocoa or Coffee?" but also the preferd pronoun and the nickname that should be displyed. This way, the badges on the one hand served as regular badges but also were used as easy conversation starters.
The colors are chosen from the official Wikidata colors and the pattern ar in a clear, technological style.
The project was built with paper.js and node.
