The project Alphabetical started in several years ago when Creative Review commissioned Dan Tobin Smith to create "a Letter A" for their Annual.
"Each Letter has a different approach but uses Helvetica as the base typography. Most are temporary installations, some use landscape and some were conceived as primarily moving image (such as Letter T).

New Letters will be added as they are finished and supporting material including work in progress will be added from time to time."
