A lot of Tableteers use ArtRage, the really unique art program from Ambient Designs. Well, Ambient Designs has just announced that ArtRage Version 2.5 Full Edition has been released and it contains a slew of new features.
ArtRage comes in several flavors for those who like to use a stylus (or perhaps their finger.) Version 2.5 Full Edition costs $25. Existing 2.0 owners can upgrade for free. There is also a free edition of ArtRage that does not contain the full range of features. ArtRage also has a UMPC optimized version in addition to a version for the Mac.
