In "Real Time" (1999) was the very first video walk that Cardiff created. It took place in the library of the Carnegie Museum of Art and begins with the participant donning a pair of headphones attached to a small video camera. Upon playback Cardiff says to watch the screen and follow along with what we see and hear for approximately 18 minutes. This piece relies on the discrepancies between what is seen on the video monitor and what is actually occurring in the library.
