Random Walks are a fun project that makes something seem to wander around the screen. It's random, but random in a way that feels somewhat natural instead of just bouncing all over the place. It's movement is random, but that randomness is dependent on the previous location of the item.
This is the first of at least 3 random walks that I plan to make in Game Lab. Game Lab is Unit 3 of Computer Science Discoveries (CSD) on code.org, but it's also a great place to play and tinker even without an assignment.
