Created by Kim Asendorf, asdfbmp is a pixel art generator app for iPhone and iPod Touch. It creates a pixel structure by using a spatial partition algorithm resulting in fields populated by pixel patterns.
You can choose from 16 bitmap patterns and 32 colours. You can adjust the minimal field size, the probability of a new division and the proportion between horizontal and vertical division.
In the draw mode you decide which field is going to be divided. The auto mode divides until there is no more field left.
Additionally there is a mode menu where you can choose extra blending modes such as pattern, fill, outline, empty, random.
