In our terrestrial view of things, the speed of light seems incredibly fast. But as soon as you view it against the vast distances of the universe, it's unfortunately very slow. This animation illustrates, in realtime, the journey of a photon of light emitted from the sun and traveling across a portion of the solar system.

Remark: The video of course ignores the effects of time dilation, in the reference frame of the photons no time passes. Nevertheless it beautifully demonstrates the immensity of space and unbearable slowness of light from within a reference frame not in motion relative to the sun.
