Ok, I don't I have a picture because I'm stupid and didn't take one.
Kiernyc and I were playing a game online. I was fighting one of the AI at my planet and my culture was acquiring his last planet. He had 3 capital ships (2 carriers and a Missile Cap, the Desolater I believe) in a VERY tight formation.
Then my culture took his last planet...
THE EXPLOSION WAS AWESOME!!!! Yeah, sure, capital ship explosions by themselves get boring, but they waves of debris went out in 3 different directions, so it formed what looked like a simple drawing of an atom:

If you can replicate this, try it out. Kiernyc saw it too.
