So, how does this work?

Tinseltown.js consists of two tiny files.

A JS file, which assigns random (or not, if you prefer) animations, assigns random animation start times, and provides several utility functions for more control. A CSS file, containing a few CSS-based (efficient!) animations, and a class-based API system used by Tinseltown.js. Choose from tnsl-flicker , tnsl-flickerQuick , tnsl-slideFromLeft , tnsl-slideFromRight or tnsl-random (see documentation for more info).
