A week ago I had a post about cardboard furniture. zthis week, I came upon something even better. A designer in Holland, created an interior of an Amsterdam ad agency entirely out of interlocking cardboard. The design is by Joost van Bleiswijk, using 500 square meters of reinforced cardboard. And get this, he didn't use any glue or screw to interconnect the 1500 separate pieces. It's pretty impressive.
