Rift is an Experimental 3D animation piece for one channel projection setting. It took interests in the concept of time and its cyclical nature. The particle simulation is generated from a NASA image of our very own Galaxy. Flipping it on its side, the viewer is only exposed to the limited two dimensions (X and Y axises) of this 3D simulated milky-way composed of millions of start particles. The piece confronts the human limitation in grasping the vastness of cosmic time and space, but highlights the advantages in the current simulation technology of the visualization of "the Big Data".
