Ruby source code minifier/uglifier?

hi
Does anybody know something about any project that can reshape ruby
source code, making it shorter and/or harder to read? Of course it must
not alter the behaviour of the code.

Maybe GitHub - seattlerb/ruby2ruby ? (Disclaimer: never used
it myself.)

With JRuby you can compile down to a JAR file or exe.
