I was inspired by Van Gogh’s Starry Night painting. I thought it would be interesting to see what his painting would look like if it was animated, since he painted a sky with wind that was painted with the intention of motion. I made each aspect of the painting into different functions, so they would be easier to place when each part was complete. I utilized many for loops in order to achieve his brush stroke affect. All in all, I think my code provides insight into what the wind in his painting would look like if it could be animated.
