@FiredGinkgo and I recently helped with a school auction project. The kids knew they wanted to do something recycled and with the Fibonacci spiral. We got to brainstorming and came across this awesome tutorial for an aluminum can wall hanging.
The kids collected hundreds of cans and hand-punched over 1,000 3/4" metal discs to create the โseedsโ of the Fibonacci sunflower spiral. Then we attached all of them to a handmade frame. The finished piece is approximately 26" x 26". We installed a metal French cleat on the backside for hanging.
This is so unique and super neat! I love both the look and the sound it makes. I definitely think you should have one for your house, but yeah, hammering 1000+ pieces into place does sound pretty daunting!
