Simultaneity Spacetime Diagram Model

Simultaneity Spacetime Diagram Model is a free software that uses light-trajectories to show the effect of relative motion when observing (recording) events in special relativity. 

In the default scenario, an explosion (an event) at the center of a right-moving stick occurs at t=0 and the arrival of the explosion light signal at each end is recorded. 

The arrival event at the left end occurs before the arrival event at the right end because the stick is moving.

How do the location and time of these events change if they are observed in a reference frame (the Other Frame) in which the stick is stationary?
