A while ago I posted on generating random point sets, and Sean Gillies suggested Halton sequences as a way of generating nice-looking point distributions. I finally got around to looking into this idea. Indeed he was correct - Halton sequences provide a very pleasing appearance for point distributions (much better than purely random distributions).
Barnes surface interpolation. I suppose the rejoinder would be to get in there and improve it!)
Keying off something else that Sean showed on his blog, I also played around with using Halton sequences to generate quasi-random sets of polygons. Here's one example, using a slightly different approach to Sean's:
Might come in handy someday for generating test data, or possibly as a visual texture.
