Flame Painting

Flame is a painting program. Everyone can be an artist with Flame and you can try it with different brush settings and paint your own flame paintings. When you change background from black to white, palette changes from additive to substactive and the feeling of the painting is very different. It's not easy to explain all brush parameters, so you have to figure that out yourself. LINK: The Presurfer

Here is an example (not mine) of what you can do with Flame.
