Bryan Mulvihill (a.k.a. Trolley Bus) is an artist, calligrapher, and tea historian based in Vancouver, Canada. His calligraphy works range from traditional to experimental, as his “calligraffiti” pays homage to the ‘cut-up’ and ‘permutation’ processes—literary methods that free the word into an open state of visual association. Mulvihill is the co-founder of World Tea Party, an interactive, transcultural, art tea salon that facilitates tea parties as a social sculpture and offers a place to gather and exchange ideas.
