before I got Corel Painter, Artweaver was the most important natural media painting tool for me.
It is still only 0.4 and far from finished, but the brush engine the design of which is very close to Painter's approach, is already capable of mimicking a wide array of natural media tools.
I have also seen a few pros use this tool (zhuzhu for example...:) )
Now, 0.4 is online.
While Artweaver is still missing important features (most prominent being the missing memory management) it is a fascinating piece of freeware and its author, Boris Eyrich, is keen on feedback and is known to quickly incorporate thoughtful suggestions.
So check it out and help make it better til 1.0!
