'duif', Dutch for pigeon, is a collection of 79 malformed pigeons against an abstract backdrop. Pigeons were the inspiration for this collection and these 'flying rats' tend to have a few 'variations'.

This project uses black png mask layers to generate the different duiven.

Each bird has descriptive but semi-generalized features to allow rarity ranking. e.g. Background: Noisy Double Quadrilateral. Body: A Black Outline with a Yellow Body and Black Feathers. Beak: A Yellow Beak. Eyes: White Eyes with a Black Outline.

Variable features are:

• The color of its outline, body, feathers, (broken) beak, bloodshot/possessed eyes, glasses.
• The presence of feather, nostrils, broken beak, bloodshot/possessed eyes, glasses.
• Bloodshot in 'possessed' eyes (very rare).

Colors are:

• Default or random.
• Vertical, horizontal or concentric rainbow pattern.
• Noisy.

Backdrops are:

• Noisy or not.
• Random color.
• A Circle, a single or double quadrilateral with random colors.
