You can probably accomplish that with the standard curses library:
http://ruby-doc.org/stdlib/libdoc/curses/rdoc/index.html

Or the ncurses-ruby library:
http://ncurses-ruby.berlios.de/

The "documentation" for the former is pretty much just a list of 
functions.  The second one seems to be a fairly direct mapping to the 
ncurses C library, so you can use documentation for the C library.  As 
far as I know, ncurses is one of the most popular libraries for doing 
manipulation of the console.
