RiverRun lets you change the
shapes and colors of objects in the stream. Click the moving pieces or
slide the controllers to change the background, colors, shapes, and speed.
How many different colors and shapes you can name? What happens to the
colors when you add more black or white to the background? How many different
colors and shapes can you display at the same time?
