3D graphic design with Blender

The project is a 3D graphic design of a room (will be called test room) and another room (will be called control room) with some simple equipment (e.g. table, chair, observation screens, pc, security camera etc.). It is expected that everything to be very simple and minimalistic. It should be bi- or tri-color design whereas security camera and some other components (to be explained later on) to be highlighted. In one scenario, test room should contain some machinery (doesn't matter which kind of as long as they look dangerous) and control room should couple of people. In this case a light bulb in control room should indicate green. In a second scenario, there should be 2 men in test room, some arrays should be directing from security camera to these 2 men and a door between control room and test room should be open whereas light bulb in control room should indicate red. This is a rough description, details will be shared later on. The work is expected to be open-source (with Blender or some other open-source software)
