Create paper flowers.
I used 1/2" strips of colorful cardstock, cut with a paper cutter. Flowers were formed by gluing the strips into circles and then manipulating them into various shapes.
I used an old wooden hoop we had around the house and spray painted it pink. I attached eye hooks on the inside of the frame to support the flowers. I used four eye hooks on the outside of the frame to support the frame from the ceiling.
Prepare motor assembly and arm.
I used two pulleys, 1 large and 1 small, and attached them to a piece of wood painted the same color as the frame. A large rubber band connected the two pulleys. The small pulley was friction fit onto the littleBits dc motor. The "arm" was attached to the large pulley.
Attach the motor assembly to the frame.
We raised the motor assembly bar 2 inches above the frame with wooden blocks, and screwed the entire thing into the frame.
Attach flowers to the frame.
I pierced the top of each flower with a needle, and thread fishing line through the flower and up through the eye hooks. Each flower was then connected to a swivel mounted a few inches from the center of the "arm".
