Wikipedia:Featured picture candidates/Lorentz transform of world line

 
Animation of an accelerating particle travelling along its worldline. The dots on the line are spaced at regular proper time intervals. The diagonal lines show the particle's light cone at that time. The other dots are random events.

This animation by User:Cyp is just an amazing addition to special relativity, where it has a much more complete caption. It illustrates very well how the proper time of an accelerating observer changes with velocity. Several people have praised this image on Talk:Special relativity so I definitely feel it fits the useful to the article criterion.
