Need to do more lisp stuff.

I haven't done anything with lisp for a long long time now. I keep reading about it, for example working out the examples from "Land of Lisp" and "Realm of Racket", but I haven't done anything of my own for work or fun for a while now. Everything at work has been LabView and Perl and Excel Visual Basic macros. Everything for school has been Java, C, and Matlab. Everything at home has been Perl lately.
