Once every 5 years the city of Handa, south of Nagoya has a huge festival called the Handa Float Festival. I'm not sure where they all come from but 31 different floats get displayed all over the city of 100,000's of people show up to check them out.
The images they make by stitching is almost 3D. I think these rugs are 100's of years old.
I think this is the #1 foreign blog for post about the city of Handa.
