Sonobe cube

This was done with 6 sheets of paper. There are many variations to this model. The very first kind of this was designed by Sonobe Mitsunobu, thus the name. I like the altenating colours and patterns. Hope to do more complex models in the future.

Fortune teller (cootie-catcher)

A fun 'fortune-teller'. Children like this game. Slide your fingers and thumb under the four flaps. The fortune-teller moves in and out by moving the index finger and the thumb.
