About
In special relativity, a light cone (or null cone) is the surface describing the temporal evolution of a flash of light in Minkowski spacetime. This can be visualized in 3-space if the two horizontal axes are chosen to be spatial dimensions, while the vertical axis is time.

The following simulation was created to help you visualize the light cone (for observer moving with blue dot at the left X-Y panel). Events from three observers are drawed with blue, green and cyan traces.
