From This is Colossal:
"Studio Wieki Somers collaborated with chocolatier Rafael Mutter to create Chocolate Mill. The piece was comprised of a giant cylindrical chocolate block that was carefully organized in 10 stacked layers, with flavored shapes used to create different geometric patterns. As a crank-turned blade similar to a cheese slicer grazed shavings off the top, the hidden layers were slowly revealed."
I would need a lot of self-control and patience because I would want to take a huge bite out of it and chew my way through.
