During my daily scan of the architecture job boards I found an article about this one night architecture competition on archinect. Of course it wasn't very vegan because the medium for the models? Cheese. Yes... cheese. I can't disagree that cheese wouldn't be a great medium to work with. Malleable, meltable, easy to use. It sure would beat foam core.
I could go off on a diatribe about how I wish there were more events like this in the architectural community and discuss the effectiveness of these events at doing whatever it is they are trying to do. But I lack motivation and writing skills and have a top-tube pad to knit.
