Crystal is a Unix mud client, released under the GNU GPL. It was originally designed and written for users of the Cryosphere, but aims to support all muds. If it doesn't work for you, please let us know.

Crystal's philosophy is to provide an interface as unclutted as unix telnet's, but with more features, such as line editing, split-screen scrollback.

Crystal has a sister project, Chrysalis, to create a modern Javascript MUD client, with a similar philosophy.

Version 0.2.4 (download here, 147kB) is current.
