Panoramic Photo Gallery

I can not read Japanese but I believe that this is a panoramic photo gallery of a Japanese storm water drainage system. The initial schematic provides an overview of the storm water drainage system and the user/viewer can then choose to look at a number of panoramic views within that system

For those interested in making these sorts of panoramas with kids there is a brief how to at

The initial schematic could probably be made with a vector graphics program like 'inkscape' (Free Open Source product)

This all makes for a challenging technical exercise that involves kids in creative design work at a cost of around $0.00
