Brush

A brush is a device with bristles used for applying ink or paint. Brush can also refer to the digital equivalent one would find in a bitmap graphics editor (such as Photoshop or Gimp) - IE, a virtual brush that can modify a digital picture. Alternatively, a brush may be used to groom hair.

Brush can also refer to untamed grassy areas, as well as so-called "Transitional Zones" - areas between canopy forests and field type habitats.

In golf, it is synonomous with the "rough" - the area outside the fareway.

Additionally, in 3D computer game development, brushes are the solid polyhedrons that make up the level geometry.
