Signals
Fans of films may find Signals especially interesting thanks to its engaging atmosphere, visual presentation, and entertainment value.
Tubes that seem to grow out of tall dry grass while recordings of bat calls can be heard. The head of a lighthouse slowly gives its binary call, accompanied by a deep circling industrial tone. An answer comes in the form of a second set of tubes, protruding from a building like cannon barrels. Both visual and auditory signals can be read as a type of abstract Morse code.
