I had trouble coming up with a concept for this project. It was so open ended, that I wasn’t sure exactly what I should do. I managed to come to the idea of depicting a storm. The user can interact with the program by pressing the mouse to show lightning or move the mouse left and right to portray how wind would behave. Caption: The user moved to the left side, as the “wind”, which swayed the trees on the bottom left. Caption: The user clicked the mouse and the lightning appeared.
