title: Curiosities in periodic precipitation patterns.
abstract: Observations have been made of several types of Liesegang patterns that are more complex than the usual concentric ring or parallel bands of precipitate. The structures observed show radial gaps, segmentation, irregular patterns within concentric rings, add the formation of spiral precipitation bands instead of sets of parallel Lisegang bands.
