How does a new media author present his work in the flesh? Find out this coming Saturday, at 4pm, when Brian Kim Stefans will read at Double Happiness at 173 Mott Street in Manhattan. Stefans' paper books include "Angry Penguins," "Gulf," and "Free Space Comix," but he is also a recognized digital artist and poet who has experimented with online narratives. (He'll be reading with Joan Retallack, author of the book "How to Do Things With Words.") Admission is $4.
