I'm cooperating on a product with my friend Rika Watanabe at the moment. It is a server appliance for a specific task in SL, and the first development versions were located in your run-of-the-mill plywood boxes. As the project become more advanced, we figured it needs to be in some sort 19" server rack. I had a texture for this ready, and in fact it started to look more professional. But at the same time boring, and too possible-in-real-life. A further complication came as the device is used to rez objects, and due to technical limitations, the objects get rezzed at its center before being moved to their location.
Thinking a bit outside the box, and a bit not-possible-in-real-life, we gathered a hollow cube would be best for this. So I started to build a hollow box, and soon it became obvious this will be a "microwave on steroids". I used a technique called "baking textures" in my RL-3D application, and developed a very sci-fi like cube. Some subtle glow effects, and some equally subtle particle effects by Rika, and voilá - a very SL like version of a cube.
