How can I work with Lisp and Adobe Flex? I am looking to build an Information visualisation project where I can display representations and interpretations of data in different visual schemes. I would like to perform the complex mathematical processing of the data using Lisp, but use Flex to render the GUI in Flash player so it can be used across platforms. I would appreciate a theoretical answer at this point, as well as an indication of consulting charges if I need it during the project.
