This is the improved version of the very popular applet that lots of people have used to link to. It can show you the way an algorithm has to be performed by using an applet that demonstrates it in an animation. In this new version, based on the WordPress Rubik Plugin, you can also show the algorithm as an image, or as a link, and use many more attributes.
The big difference with the plugin is that this applet can be accessed from the url "wp-content/plugins/rubik/cubeapplet.php". Just add your own parameters, e.g. "?alg=BLURRED" to show the animation. Because the page does not show any other stuff (except for a small ad and a donation link) it can be embedded on your own site very easily, even if you don't have a WordPress site.
