PenGo, the developers of the painting application PenGo Paint have developed BrushPen, a touch pen that can be used in conjunction with their app to bring touch screen painting to the next level. The Paint app itself is a multi-feature painting program for tablets or other touchscreen devices with an array brushes and tools in and of itself.
The BrushPen further simulates the actual act of drawing or painting. The strength of drawn lines is even affected by the amount of pressure placed on the brush when applied to a touch screen. The pen itself has three different tips that include thick, thin and brush. The pen does not need to be used only with the Paint app but is compatible with any touch screen app. Via:[PSFK]
