Here's how ARES Commander Edition looks like on Ubuntu 10.04. The software is localized in many languages, and automatically adopted my operating sytem's locale (which is French as you can see).

Those who read Ricky Jordan's blog post on DraftSight for Linux will notice the uncanny ressemblance (DraftSight is based on ARES).

The user interface (programmed in Qt) is very clean, by default icons are large, but they can be set to small in the preferences.

If anyone's wondering, these are the 2D drawing and the 3D model of my custom-made home computer desk (dimensions are in inches). But I didn't model the keyboard, mouse and SpaceNavigator; those I found on 3DContentCentral.
