Waveform generation tools

Automatic, semi-random ".signature" rotator/generator

signify

Automatic, semi-random ".signature" rotator/generator

Signify is a neat little program that allows a random signature to be generated from a set of rules. Each "section" can be one of an unlimited number of possibilities, each with its own weighting so those really cool quotes can appear more often than others. Sections can also be placed next to each other vertically to create columns. Each section can be formatted independently as left/right/center and top/bottom/vcenter.
