How To: Make a cool paper box

The box requires 2 6"x6" sheets of paper in 12 colors, that is 24 sheets in total, as well as one 6.25"x6.25" and one 6.5"x6.5" piece of paper, both preferably of the same color. Construction will also require some paper glue at certain points. The construction of the box is sectional; there is an outer box, with the inside "concertina" mechanism formed from 12 identical units glued together. The sectional nature of the construction would lend itself well to people working in groups in a class setting.
