Currently I'm reading up on the following computer languages:
Python - fun, easy to learn, batteries included
Boo - fun like Python, but with macros and type declarations so that it can run fast.
Erlang - very brief code. I'm impressed by how concise the Wings3D source code is.
Typed Scheme - Scheme with type checking. (Could in theory run fast.)
I may try implementing my old "Dandy" game in these languages to see how they feel.
