The new bristle brush feature gives you the ability to add real bristle brush effects right in Photoshop. It even responds to the tilt of the Wacom pen. To see the angle of the brush there is a convenient preview window that comes on when you select a bristle brush. It can also be turned on or off inside the Brush Options panel by clicking the icon at the bottom. You can also click inside the preview window to change the angle of view from a side view to a top view.
