[8/30/11] The new ACT-R applet is now available! The applet
includes all the functionality of the standard application except for
the ability to save and load model files. Instead, the applet
incorporates built-in models derived from
the CMU ACT-R
tutorials. The applet is primarily intended for beginners or
curious users who would like to run ACT-R without the investment of
installing the full system.
