I came across this interesting series of videos in Ikea's archives. Called the "Square Meter Challenge," Ikea's designers were tasked with using Ikea products to create livable, functional, comfortable space in some seriously tiny footprints. They start off with on-screen drawings explaining the concept behind each space, then show you what it looks like, and how it would work, in real life.
