Charpentier’s three deck illusion - UK Version
I thought this looked interesting so I raided my loose change box and have made a UK version of the Charpentier illusion which uses 14 x 1p and 24 x 2p pieces. See the original https://www.thingiverse.com/thing:1293523 for a full description of the illusion.
A couple of years after posting this, I was walking to my office and just happened to be carrying two empty PC boxes and one full one and wondered how well this would work on a larger scale. The answer is BRILLIANTLY! So well that I had everyone in the office try it and it was amusing to see the baffled looks on their faces.
