This page demonstrates the Layer Slider.
HOLY CRAP!!! MASSIVELY powerful slider options! 112 different 2D transition types; 100 different 3D transition types, and can also add custom transitions! Can select as many different transitions as you want. You can add an unlimited number of layers (overlays) over the image. Layers can be text, images, html, audio, video, and dynamic content (e.g., posts). Each layer can have it own transition effects (entrance and exit), styling (including things like transparency, etc.), links, etc. The UI is incredibly easy & straightforward to use.
Has short codes and php codes, so can be inserted anywhere on any page.
Also has event callbacks so you can fire custom PHP code in response to any of 8 events associated with the slider
