Thanks to a post on AV Club, that you can read here, I found the coolest video and idea. Instead of having a sign-off screen or test pattern at the end of the night, a Canadian TV station decided to show a program called "Night Walk." Night Walk showed views of Toronto in first person while jazz played in the background. An insomniac's dream.
Here's the description straight from the fan website:
An alternative to Global TV’s overnight test pattern on its’ over-the-air stations, the 60-minute Night Walk (with two 2-minute commercial breaks) was scheduled to begin airing at 4 a.m. ET on the morning of May 3, 1986 and the 60-minute Night Ride followed by the early morning of June 22, 1986. Both shows were filmed in one night, on May 2, 1986 between 10 p.m. and 1 a.m., in and around downtown Toronto using the relatively new Steadicam camera stabilizer. Night Moves, a 30 minute episode, was also filmed in one night, on October 5, 1986, and began airing before Night Ride and Night Walk beginning at 3 a.m. ET on the early morning of Dec. 7, 1986. The second 60 minute version of Night Walk, featuring the same soundtrack as the first episode and footage from the Night Moves shoot, made its first appearance by late May 1987. These four were the only episodes made, and they were replayed nightly until the summer of 1993. The shows are now considered early examples of “slow TV.”
