Certain pixels in textures (such as the core texture, or the cannon texture,) should be bright even if the block isn't lit, or emitting light (if you don't know what I mean, go look at the spiders and endermen in minecraft, their eyes always glow.) A pretty unimportant change to be sure, but I think it'd add a lot to the aesthetic. Computer stuff shouldn't ever be completely dark, it ruins their aesthetic appeal :c
Could even animate the textures to blink :3
