KALEIDOSCOPE PAINTER

Choose the "Auto" feature to see the kaleidoscope fill in with its own patterns, clear the canvas and try it on your own, or try a different brush size with this fun online painting tool. Drag your mouse across the pattern for some spectacular effects, but be careful, it might become addictive!
