Towards the end of the project, I needed a few more of the pixelly images at short notice, to illustrate the essays and about pages on the site. Rather than bother Geraldine, I reached for Processing to see if I could match the look of the homepage imagery that she had created.
I came up with an applet that used a bit of blurring, a bit of distance fall-off, and a bit of perlin noise to create the effect that we were looking for (decorative, obscured, but related to the overall site). Here's an example of the imagery created from a picture of Scott Snibbe's Three Drops that we used on the page for Jennifer Frazier's essay:
You can see the full applet and source code here, and I think it's a good example of how a generative solution to design elements can keep a project flexible right up until launch (and beyond).
