Revised Design Statement

We are exploring color, shapes, turtle graphics, and the effects of unpredictability on an image in our design. We made a series of interesting and pleasing images that change in unpredictable ways. Our incorporation of several design elements makes every image dynamic and complex.


Shapes and Turtles:
The background of each image is a series of concentric shapes ellipses or rectangles with centers based on a given height and width. The spacing between each shape and the number of shapes in each image change depending on a given number. On top of these concentric shapes, in the foreground of the picture plane, there is a geometric design produced using turtle graphics. The design changes dramatically in each image.

Color:
Each image has a variety of colors in the concentric shapes. This variety is produced by making many unpredictable shifts on the color wheel with a given number. Because the color combinations are not guaranteed to be entirely aesthetically pleasing, they have the potential to be incredibly complex. While the colors of the concentric shapes change in each image, the color of the turtle graphics is always white. This provides an obvious contrast and a juxtaposition between the predictable, patterned nature of concentricity and the unpredictability of the hue-change color scheme and between the wild variability of the turtle graphics and their constant color. 

Design Goals:
By manipulating many elements of the images, we hope to disrupt the rhythm, balance, and texture of the canvas in unpredictable ways! While the concentric shapes are constantly changing in color scheme, spacing, and density of shapes, they are still much more static than the turtle design, which dramatically varies in shape and pattern in each image. This relative passivity in the concentric shapes emphasizes the turtle design, pushing it into the foreground and giving each image depth. The difference in the nature of turtle graphics (lines without a fill) and the solid nature of shapes provides every image with an incredible contrast in texture.

Revised Technique Statement 

All of the variation in our image is based on n, a number from 0 to 999, and uses modulo to cycle through a series of possibilities in each category. Each series of possibilities is based on a different prime number and, as we have varied categories and several distinct possibilities within each category, our procedure is able to produce at least 1000 distinct images. 
We used GIMP tools (drawings that we then converted to images) to form concentric shapes; turtles to make various patterns; relied heavily on recursion, repetition, the map procedure, and compose; and used lists of shapes, colors, and scaling values.

We know that our procedure will produce one thousand unique images because we heavily incorporated modulo into many elements of our procedure, using different numbers each time. This means that the attributes of our images are cycling through lists of possibilities- each with a different length. These lengths do not line up equally, so the cycling will become aligned in different ways once each list of varying attributes has been cycled through once. When we multiplied the length of these varying possibilities (the ones using prime numbers)together, we got a number greater than one thousand. 

We have chosen three values of n that especially represent the variability of the images in our series-- n= 7, 500, and 145. 
Points of Divergence:

>We decided to make the color schemes using iota lists that were passed through mathematical formulas rather than by predefining triads, because we wanted to include more ways for the color schemes to vary. 
>We went from images using image-select-polygon on top to turtles because it was easier, less overwhelming, and more attractive.
>Our concentric shapes were going to be images but they're now drawings-- we thought it would be cool to do polygons with images, but we had trouble turning lists into coordinates for the polygons.
