Unfortunately, I don’t know who produced this, but its very relevant to my own work. Here, whoever produced this is showing their audience the correlation between time and building height. I think it also shows the audience something about social changes and human advancements in construction. I can relate my own timeline to this. I think I could make something which would engage my audience more, doing the same thing but with 3d models of each building, getting people to put them in order.
