To measure eye movements of our research subjects we use an SR Research Eyelink 1000 eyetracker. However, while SR research provides libraries for C, python, matlab and a bunch of other programming languages, they do not have a library for lisp.
Of course, my experiment was already programmed in lisp. To solve this, I wrote a foreign language interface between lispworks and the eyetracker's C-code, which enables you to call the C-commands in lisp. For example, to calibrate the eyetracker you can call (eyelink:calibrate).
The lisp library is available here, please see the instructions at the top of the file for how to use it. This is very much work in progress, so please email me if you have any remarks or improvements.
