The color cube was from a pattern, but he does make up his own arrangements all the time.
The cars and blocks reminds me of another Mondrian entitles Composition in Oval with Color Planes 1 . I think he was putting the cars on their homes. I love that John is a builder and creator.
Butterflies are known for their unusual life cycle that includes a spectacular metamorphosis from caterpillar to a colorful winged adult. They have an erratic yet graceful flight pattern that attracts attention when they pass. The Ancient Greek word for butterfly is psȳchē, which means soul. I particularly admire their symmetry and kaleidoscope of colors.
