Material Testing for M1S1. In these renderings I was trying to see how could I marry the main central core with the cell bodies. I thought about a wire meshed based material for the cells/viruses, since cells and virus are transparent when looked under a microscope. For the central core of the building being consumed by the cells/virus, I thought of a very rough material like Precast concrete almost as a statement by the building trying to fight and defend itself from the virus.
