Paper Toys

My first paper toy was a set of chickens, but unfortunately before I was able to get home to document them they were trampled and took a beating. I restored them for the image below, and took a video prior to completing the the setup, as a test run, which can be seen after the image.

For the next toy I was thinking about how I can use the ultrasonic range finder and have it make sense, so I came up with the idea of a baby bird being fed by its mother. It gets excited whenever its mother is near with a worm so it jumps up and down and I made a slight modification so it opens and closes its mouth to eat the worm, the closer you are the more excited the bird gets. When you are out of range the bird saves its energy and waits patiently. Image
