Mondrian's Square is an assembly puzzle created by Tom Jolly in 2021. Building on concepts from his puzzles Little Window (2011) and Open Window (2012), and with a name inspired by the abstract geometric paintings of Dutch artist Piet Mondrian, Mondrian's Square turns those two designs inside out, putting the odd-shaped pieces on the outer layers instead of on the inner one. The result is a visually appealing piece of art that's just as pleasing to look at as it is to play with.

The goal is to find the single solution to fit the four pieces into the frame. Made of anodized aluminum and sandblasted brass, the precision machining and finish make for very satisfying movements, and the assembled puzzle has a nice weight and soft feel in the hands. A hole through one corner to attach a chain locks the puzzle in its solved configuration and allows it to be used as a keychain or ornament, or it can be worn as a pendant with the included nylon cord.

It makes an excellent companion to the larger six-piece .

Mondrian's Square ships in a solved and locked configuration.
