It is the concept of this image for the display to evolve over time, changing lighting conditions based upon the time of day, cloud formations moving across the frame, and the growth of the foliage over time based upon a random number source such as ambient noise in the environment which the shirt is being worn in.
This growth would be recorded between time the shirt is worn, meaning that each shirt running this design would have a unique look as the image evolves over time.
This image was created in Adobe Photoshop with heavy use of layer style effects in order to more easily create shade effects whilst still only using three colours.
