A very belated Wed. recommendation, but you'll have to excuse me this week, my sleeping habits are getting hugely distorted.
Today's recommendation is a sketching/paint/design/art program, Art Rage, that's one of my personal favorites for its uniqueness and special features that you don't really get anywhere else. It's fun, extremely easy to use, won't get you lost in options like with photoshop (for inexperienced users) and simply gets the job done!
You just have to try it out.
Each of the tools in ArtRage is designed to work like its real world counterpart (minus the smell of paint thinners, and that piece of glitter you just can’t get out of the carpet).
Thick paint smears and blends, pencils and chalks smudge, and markers work just like they do in the real world. Many of the tools can be adjusted to give different effects. You can paint with thinned oils, use wet or dry markers, soften your pencil and control the hardness of the crayon, and much more.
You can check out some work that has been done using it here.
There's a free starter edition available on their website.
Scribble awaaaaay peeps!
