Jonathan Glazer's Under the Skin focuses on the idea of perspective. The film depicts how a being from another plant might come to understand what being human, and more specifically a woman, might mean on Earth.
Many times an outside perspective is shown in film by having the subject look through a window, or something of the like. For this title sequence, abstract "ice" pieces (created in Cinema 4d) were used as the "window", the footage was then edited in way that would suggest perspective through an eye. The distorted nature of the ice is symbolic of the many "distortions" that may influence our perception of of the world around us. The fog (created with turbulence FD) is also symbolic of things that may come to "cloud our judgement" as well as the fluidity of our understanding.
The type animates in a way that manifests the film's emphasis of phenomenology. The ending scene shows the title through the shards of ice which alludes to a brief moment of clarity that can sometimes disappear just as quickly as it came.
