Log 17 (Fall 2009), guest edited by Mark Foster Gage and Florencia Pita, features essays and conversations focusing on relationships between new media and materiality in architecture with an emphasis on sensation and affect. Contributors Sir Peter Cook; Joe Day; David Erdman; Jeffrey Kipnis; Sylvia Lavin; Alex McDowell; William O'Brien Jr.; David Ruy; Mohamed Sharif; and Teresa Stoppani. The cover features a 3-D drawing by Tristan Eaton and the issue comes with a pair of 3-D glasses (in lieu of the traditional Log postcard). Conversations Thom Mayne and Hernan Diaz Alonso discussing drawing; Peter Zellner and colleagues discussing the pretensions of form; and Todd Gannon interviewing Georgina Huljich and Marcelo Spina, the curators of the Matters of Sensation exhibition held at Artists Space, New York, in 2008.
