Aegis

A window manager for X11.

Aegis is a followup project of 4 Kahakai programmers who left the Kahakai project because it is based on bad and confusing code wich makes it difficult to maintain.

Aegis can be found here: http://aegis.thegraveyard.org/

it is still a very early version that basicly hasn't got any functionality yet... but they are getting there and updating there code on a daily base.
