Think of tags as like a book index where you find words and which pages they are on, the same principle applies here. Although it's taken a stage further so it might not be the word, but the subject, so for example if you're looking for things to do with fractal gradients for example. A tag may bring back posts with gradient files, as well as posts that discuss gradients, or tutorials about them.
This script uses a combination of linked juliascope and elliptic variations together with splits and a bipolar final. The result is tiled through log_tile2 and another final is added from a list of selected transforms.
