Snow had the idea in 1964 to create a film where a camera moved "in every direction and on every plane of a sphere". During the late 1960s he created three films that experimented with camera movement: Wavelength, Standard Time, and <--->. He researched machines that could automatically move a camera in complex ways, particularly surveillance devices. The Canadian Film Development Corporation gave Snow a grant of $28,000, and he received additional funding from the Famous Players chain of theatres.
