Scriptographer is a scripting plugin for Adobe Illustrator™. It gives the user the possibility to extend Illustrator’s functionality by the use of JavaScript. The user is no longer limited to the same tools that are used by most designers. Scriptographer allows the creation of mouse controlled drawing-tools, effects that modify existing graphics and scripts that create new ones.
Check out the scripts and tutorials.
Also worth checking out these very, very, handy scripts from Hiroyuki Sato which could possibly save you hours of work in illustrator.
