Here`s a 28mm-scale terminal for Fallout: Wasteland Warfare. In the Fallout computer games, such terminals can be hacked to unlock access to locked doors or safes, or they might give you control over automated gun turrets that might otherwise blast you. You can even play mini-games on some of them, or discover logs and emails that tell the story of the world before and after the final terrible war of 2077.
In Fallout: Wasteland Warfare, the terminals help make the playing field more immersive, and they play roles in certain gaming scenarios.
In the real world, these pieces are tiny, and therefore challenging to paint. However, aside from the display screen, I think this one looks appropriately worn.
