DUIM is the Dylan User Interface Manager, the GUI library used in the Functional Developer Dylan system. Duncan Rose is porting it to Common Lisp.

DUIM is a nice easy to understand user interface framework. I used it quite a bit to develop a number of Dylan programs. Many of my creatures programs and other things for example. It fills a similar space to the LispWorks CLIM library.

Hopefully Deuce will also be ported. Deuce is the emacs-like text editor for the DUIM framework. Thanks to John Pallister for the heads up.
