For me, reading Lisp is a tactile experience as well as a visual one.

Lisp code is a tree, and emacs has a lot of neat commands to let you move around the tree (up one level, down one level, leaf forward, leaf backward), and I find myself doing this whenever I have a piece of Lisp code open to "feel out" its structure.

It's a little different, and maybe less like "reading" than understanding a piece of Python code, but I like it.
