A lot of people seem to want to build models of the Roman Colosseum for their projects. The most successful of these, judging from the mail I get, seem to be built out of sugar cubes held together with rubber cement. But you can also use Legos for this Colosseum project.
Increasingly, though, people build models of the Colosseum online. Many people use Minecraft, and this video shows you how to do that. With Minecraft, you can build a more accurate model, but you can’t take it to school and show it off.
