I’ve been playing with a really cool online painting tool called “Flame”. It’s a Flash app, so no need to download anything.
From the site:
Flame is a painting program, it belongs to my ‘I am Artist’ experimental project. I think with tools which inspires you, everyone can be an artist. You can try it here, change 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 I leave this for your experimentation.
Playing around with it for a few minutes I was able to create a couple of really neat looking abstract images. The best way I can describe it is painting with chaos and light. Definitely check out the gallery of what people have been able to do with it. Warning, it can be a bit mesmerizing and addictive.
