MoSculp from MIT CSAIL, Google Research and UC Berkeley is an Interactive Visualization of Shape and Time

From MIT CSAIL:

We present a system that visualizes complex human motion via 3D motion sculptures—a representation that conveys the 3D structure swept by a human body as it moves through space. Our system computes a motion sculpture from an input video, and then embeds it back into the scene in a 3D-aware fashion. The user may also explore the sculpture directly in 3D or physically print it. Our interactive interface allows users to customize the sculpture design, for example, by selecting materials and lighting conditions.
