This is a game where you get to program a human computer. No electricity required! This method works even when the power is off. It’s also a way to re-use your old plastic bottle-tops and turn them into plastic pixel art. These designs look really beautiful if you put them up in the window. The game we played is called ‘Secret Shapes’. Each team is given a different shape to produce and a bucket of recycled bottle-tops. Once the shape has been designed then the team writes down a set of detailed verbal instructions (can be numbers or words in any language). The other team may not see the shape but needs to try to recreate it exactly by following the instructions as carefully as possible. Our instructions were pretty good, both teams ended up reproducing the ‘secret shape’.
