"Mouse to control paint brushes. Space to add more brushes. Z to delete all brushes. X to clear background. C moves all brushes to a random location. Hold mouse button to make the brushes move away instead." -ecker00 Some cool stuff you can do with 10+ brushes: 1. Put your mouse in the middle of the stage and hold down the mouse button 2. Click "c" a bunch of times 3. Go to one of the corners and hold the mouse button, then let it go 4. Hold the mouse still and keep clicking the mouse button while the brushes are trying to follow you. It looks really cools if you do it fast 5. Add about 10 brushes and make a wide circle with the mouse.
This a remix of @ecker00's project. I only changed the brush size and the speed of the brushes when they follow the mouse. Note: In Butterfly Painter One, you could only add seven brushes. But in Butterfly Painter Two, you can add as many as you want. Just keep in mind that after 40 brushes it gets kind of laggy. It looks super cool, though :-) Enjoy!
