For programmers
One of the main languages used at NoteHeads is ANSI Common Lisp. Lisp has been called "the world's most powerful programming language".

Nevertheless Lisp and other dynamic languages remain largely unknown or misunderstood by many programmers and software managers raised on more conventional languages, though the situation is changing due to Java (which owes a lot to Lisp, though it lacks its abstractional flexibility and expressive power).

Lisp has evolved continuously since 1957, to a large extent within the Artifical Intelligence research community, and it is now an extremely powerful language especially suited for large-scale systems, exploratory programming and symbolic and numeric computation, just to mention a few areas. It is eminently suitable for writing complex commercial applications such as Igor Engraver. Why not read this article by Eran Gat at NASA about Lisp vs C/C++ and Java?
As a small service to the Lisp programming community, NoteHeads is now able to present the following Macintosh Common Lisp free software:
 an OMS 2.0 interface, Version 2
 a compact but powerful Defsystem
 a Palette Handler Utility
 a Window Avoidance Utility
 a Font Chooser
