I’m very excited about a new face mask I designed.  You can order it online! I was inspired by two tweets I saw within minutes of each other on July Fourth.  First, Médéric Gasquet-Cyrus, a professor at Aix-Marseille, posted a picture of  his colleague Pascal Roméas wearing a “triangle vocalique” T-shirt designed by the linguistics YouTuber Romain Filstroff, known as Linguisticae.
