The animation fancifully interprets the formation of electricity in the cloud. Inside a thundercloud are countless specks of ice dust floating and bumping into one another. Their collisions build up an electric charge that overtime fills up the entire cloud. The sculpted and hand-drawn particles resemble pre-civilization cave paintings, implying a certain primordial theory of creation. The lightning is also hand sketched on the same level of finesse. The watery iciness of the particles calls to mind the idea of a frozen fountain.
Please pick up a piece of ice and observe how the melting ice glistens across its surface for a scrupulous appreciation of the animation.
