I wanted to add the Obelisk of Light (NOD), but feared not that many would understand it :p

I played all C&C games probably, from the very first DOS one ;)

Nice example.  Although I thought it was slightly confusing by BuildingLaser being above BuildingUpgradeDecorator, but that is probably me missing the direction of the generalisation.

Also the IBuilding label is missing from the Normal Building.... Your other site mentions it though! :)
