The Pixel Flow procedural texture produces an abstract pixel pattern effect that can be animated (figure 1).
Figure 1: The Pixel Flow texture applied to a Diffuse materialUsed for dull, non-reflecting materials or mesh emitters.
Time - Provides control over animating the texture effect.
Frequency - Provides adjustments for the horizontal and vertical frequency of the effect.
Density - Controls the density of the pixel pattern.
UVW Transform - Positions, scales, and rotates the surface texture.
Projection - Sets how the texture projects onto the surface.
