REBOL is an interesting language. It's free to download, available for both Linux and Windows, and quite small in size (MB).
UPDATE: Carl's comment on building REBOL from source, in the REBOL repo on Github, mentions Android as a platform that REBOL can be built for. Interesting ...
It can be used at the command line for useful one-liners, in command-line scripts, and even to write GUI programs.
It has built-in support for some common Internet protocols.
And many other features.

REBOL was created by Carl Sassenrath, who also was the main designer of the Amiga computer and OS, a very advanced PC for its time, including multitasking and advanced multimedia when almost no other computers had it.
Main REBOL site for downloading the language interpreters, documentation, examples:
REBOL is now open source:
Hacker News thread about the open sourcing of REBOL:
Has interesting points. More than one commenter pointed out that REBOL was an influence on JSON, which was News (heh) to me:
