Ananya Curves

From Ananya Systems:

Ananya Curves replace the pen tool in programs like Adobe Photoshop and allows users to draw and trace with ease. That's because all the control points are right on the curve. You do not have to pull tangent lines in order to draw or change the curve. This makes Ananya Curves easier to learn, faster to use, and virtually eliminates rework. When necessary, even rework is faster. Now artists and graphic artists can pay more attention to their drawings and tracings, and less attention to their tools. You can use Ananya Curves as a plugin for Adobe Photoshop or as a standalone program. Also, all curves can be saved as a Postscript file, which can be used in programs such as Adobe Illustrator and Corel Paint Shop Pro.
