I was inspired to do this after I saw a topic on BZP asking the same question. The Coliseum in Metru Nui has a very distinct shape when shown in the Metru Nui skyline but appears with just one tower in the movies and comics.
I have been trying to figure out how to make a building that has the shape seen in the skyline as seen from each Metru. The following screenshots are a quick CAD model I whipped up last night to try to answer this question.
If anyone has any thoughts on what the Coliseum actually looks like, I’d love to hear them!
