Scriptographer is a very nice tool. You can use javascript syntax to create your own tools for Adobe Illustrator. I formerly worked in processing and used whether the AI-Export Libary or made screenshots. Now with this tool i’m able to directly made custom pencils in Illustrator and free myself from the tools that thousands of designer use everyday.

How does it work? You work with an API. There are basically four events: init, mouseDown, mouseUp and mouseDrag. So nothing special for people who are well familiar with processing or graphic scripting. The only thing to get into is the API for the Illustrator-specific tasks.

Finally you can abuse the software and work on experimantal edges like autechre does on music. There was an early piece of softwareart called auto-illustrator that lead into that direction early, but the auto-illustrator really lacked on performance and shareware-fee.
