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.
Using bSwirl again, good one this, you can spin it out or in. Then you add some spherical action, with a good old fashioned Juliac at the end. You can get some tunnel like effects with curves.

Another bswirl attempt this time with heavy use of hypertiling and some blur for the glow, and a little post symmetry thrown in because it looked more… well… symmetrical ! 🙂
A new bSwirl game has started, you can get all kinds of cool images by tweaking what’s already here. Adjust parameters, move the triangles.
