Charlie // Processing Voidray

Exploration of "if" conditions, allowing the artifact change position depending on where the cursor is located

/**
 * Easing.
 *
 * Move the mouse across the screen and the image will follow.
 * Between drawing each frame of the animation, the program
 * calculates the difference between the position of the
 * symbol and the cursor. If the distance is larger than
 * 1 pixel, the symbol moves part of the distance (0.05) from its
 * current position toward the cursor. Depending on where the cursor
 *is located compared to image, image will turn
