   CYBURDINE IMAGES — "Black Gate"

   The house materials here are cinema's: a true black gate, a warm print-white,
   and one hot signal colour borrowed from a safelight. Where Systems is
   anodized graphite and the Sound Factory is newsprint and riso ink, Images is
   the darkened room the projector points into — letterbox bars, frame lines,
   timecode, and type set large enough to be read from the back row.

   The wordmark and the network menu are shared across every Cyburdine
   property; everything below them is this site's own.
   ========================================================================== */

   properties read as one company. Condensed is the display face; Mono carries
   every slate, designation and spec row. */
