After Aperture is a CG fan film with beautiful atmospherics and an understated elegance that attempts to explain what happens to Chell after she escapes from Aperture Science in the video game Portal 2.
Apparently the creator Zachariah Scott drew inspiration for the film from a sketch he saw of Chell sitting on the Companion Cube in the rain, and even though this short lacks action it has definitely captured the mood of life after Aperture.
