So the idea of other-worldly beings who communicate by flashes of color might strike sparks even if the message—Jonathan's proof that the Wheels are intelligent which saves their planet from unscrupulous land developers—is monochromatically silly. As little Wheel finally demonstrates his understanding to Jonathan's elders by staging a display of Christmas lights, this slight tale functions best as a sort of sci-fi greeting card.
