The texture was created simply by creating basic shapes, manipulating them and applying photographs as overlays to make it appear more lifelike.
I started with a basic grey rectangle, then applied some smaller, light rectangles in the centre to emulate lightbulbs. I then applied an outer glow to these shapes, and a gaussian blur to soften the shape. A plain white overlay was applied on top of this, acting as the plastic/frosted glass, and the metal frame was constructed by using an inner stroke on the base rectangle, then adding bevels, inner and drop shadows to give it a little shape. Finally, the texture overlay was applied and the layer set to multiply to give it a worn appearance.
I aim to add some text to the texture when I can, just to make its purpose clear (it kind of looks like a grill thing at the moment)
