Back in 2006 –when I was studying CS at Rollins College– I wrote a Scheme (subset of Lisp) interpreter that also shows a visual representation of linked lists and function calls. You can check it out here: http://davidpilo.com/pvts/
The interpreter was written in Java and while it does not support the full R5RS grammar it supports quite a bit of it (see http://davidpilo.com/pvts/language.html)
> One of the interesting debates in Lisp circles is the question of whether or not SchemeLanguage should be considered part of the LispLanguage family. There are more than a few Lispers (and perhaps a few schemers) who think that the LispSchemeDifferences are sufficiently large that Scheme should not be considered to be a "Lisp". This topic has spread across many pages, so this page has been created to quarantine this particular HolyWar.
And one interesting reason why not:
> The philosophies of the Lisp and Scheme communities have diverged quite a bit. SchemeLanguage focuses much more on FunctionalProgramming; CommonLisp on metaprogramming and multi-paradigm programming (especially OO with CommonLispObjectSystem).
