The 1997 one really happened and it is very accurate.
See the actual photos here:

The last one is the same as the one I took but you can simulate all of them accurately. Even Io, not mentioned in the text, is visible on these pictures.
As for the next events, they are also very accurate but no pictures have been issued yet !
(The only thing Celestia doesn't do here is the light time delay. Therefore the actual time of these events are slightly different: From 30minutes to 45minutes depending on the earth-jupiter distance)
More special phenomena to come....
