What you are looking at is a combination of clock and thermometer made from recycled coffee cups. I checked out the blurb from the eco company that makes them to see if I could figure out how it was done. I’m still none the wiser… but apparently it starts with them cups out of your vending machine being collected, cleaned, shredded, striped, squashed, sanded and all sorts of other stuff.
The credit for this work (and these before-and-after pics) to the Cornish based company ashortwalk. Good work guys. I’m still confused, but that’s just me.
