Modular Home of the Future. (Jetson Green, 12/15/2015)
Just like the classic video game its name comes from, Tetris House is comprised of a series of blocks, which can be slotted together to create the desired layout of a home. Various accessories and add-ons can also be attached to the exterior façade of each home. Each Tetris House is built by placing the blocks (each of which contains a room) side by side, or one on top of another. This style of building is very reminiscent of shipping container architecture, though no containers were actually used.
As for the music, Sound Hound tells me, "There were no close matches."
