Below are two java applets that you may use to connect to Voregotten Realm. The first doesn't support ANSI, but is better suited than the second to roleplay (it got a separate input-line with recall buffer: use the up and down arrow keys to scroll this buffer).

This second Java MUCK client supports ANSI colours and some ANSI attributes, but it is a little buggy (the backspace is not echoed to the screen when deleting characters) and doesn't have a separate input line with recall buffer (click the button below to connect):
