From the developer:
WowPaint brings back the fun in drawing! The standard pen and eraser are complemented by a Soft Pen, a Glitter Pen and a 3D Pen (in three variations) that produces stunning brush strokes reminiscent of pipes or cables. You will also find Smudge, as well as a similar tool called Drag.
Use your left mouse button to draw or to select tool, size and color. Right-click (anywhere) to toggle the panels on/off, so you can draw in true fullscreen mode!
You may want to check out more Mac applications, such as Smith Chart for Mac, Keynote Action Pack or Piranesi, which might be similar to WowPaint.
