I made this for J over Christmas. He enjoys working on mathematics problems for fun, so I thought he would enjoy playing with this cube while pondering. The cube is a pdf download from Satsatoku
www.sasatoku.co.jp/hp/present/paper_craft/index.html">here.
Here's a video I took of J playing with the cube, opening and closing it. You can see it starts out with 6 designs on the 6 sides. After you turn it "inside out" there are another 6 designs that appear on the outer surface. I shot it using my little Canon digital camera without audio. This is the first time I've tried to embed a video from Flickr, so I hope this works. Also, I didn't downgrade the quality but I could try doing that for faster stream. You can watch it
here, also.
ETA: 1/12/09 I've uploaded a smaller file size of the video so it should load faster. If this doesn't work, somebody let me know? Thx.
