To recap: Diane Rinella is a genius.
This Star Destroyer is actually a wedding cake for Star Wars super fans.
The cake was made by Diane Rinella of Bewitching Elegance and had working LED for the engines; you can see the photo of the slice cut out by the bride and groom.
The reception was in a sound stage at Kerner Optical (formerly of ILM) and was attended by several dozen 501st Legion members in full Storm Trooper armor.
