>>58199414>>58199430Joking aside, it's a good question. The Giga is obviously based on an English building (I forget the name), but the normal version doesn't have an obvious shape. Some say it's a reference to Mecha Godzilla, but the fake Tyranitar from Pokestar Studios and the Paldea Paradox play this role better. The inhaler, urinal, and lighter are good as a joke, but they don't explain its true origin.
Since his Giga and Evolution focus on urban architecture, it would only be urban modernist art unless someone has a better explanation without falling into satire.
