Adaptor is a free and cool jQuery carousel plugin. It can render both 3D and 2D transitions, although at this moment only Firefox and Webkit (Chrome and Safari) have the necessary support to display the 3D effects. All other browsers (including IE6) will fallback gracefully to a simple fade transition when using the 3D effects.
WooThemes created this great responsive image carousel and gives it away for free. The plugin works with jQuery and it is loaded with many features. It can adapt to various content sizes, can load both images and video and works on all modern browsers.
