"Feathers perform a number of functions for a bird. Firstly, they provide insulation, this is very important in a warm blooded animal (body temperature of most birds is maintained at around 40C). It is believed by most scientists that this insulating effect was the primary force driving the evolution of feathers, i.e. ancestral birds developed feathers to keep themselves warm. Feathers also protect birds from UV light." [1]
I am going to be using this quote and fact about how feathers work and what their job is, to build on my concept and model. This iterations within my model will occur due to changes in Light, i.e. the time of day, changes in temperature, i.e. seasons and also changes in weather, i.e. sunshine or rain.
The iteration for the time of day will be represented by the overall coverage of the tunnel that my objects cover. The iteration for the change in temperature will be the objects getting thicker, and more dense, to relate directly to the insulating properties of the feather.
The iteration of the weather, rain or sunshine, will be represented by changing the overall span of the tunnel to cover a greater distance.
