presents:



- a ball of 12 patches -


can you imagine a body that looks like a circle from six different sides but is not a ball?

if you are very smart and skillful, you can build this body of paper or cardboard.
all you need is twelve of the patches that are depicted below. when you glue them together take care allways four of the 90-corners meet each other and three of the more-than-90-corners meet each other.
you think this does not work? i think it does. there must be six points where four patches meet and 8 points where three patches meet.
please send me a foto when it is ready!

...well, nobody sent me a photo. so i built the ball myself. see
here what i have done!

here is a video of the cad-model
