Here are some screen shots taken from DEU 5.3. You can click on any of these icons to get a full size (640x480) image.
Note: these screen shots have been taken in October '94. DEU 5.3 has been improved since then, but they should give you an idea of what it looks like. Click on the ``Up'' button at the bottom of this page if you want to go to the DEU home page and grab the latest beta version.
