or place it in exactly the same location as the bomb one in the sale window?
I, for one, won't be buying them unless they appeal to me visually. If I can't see the complete visual effect, and can't find some one else who has bought it to show it off, chances are slim I'm dropping 15k on it.
That said, if there had been a display of the pixelated arrow from the last nexus, I might not have bought it for 8k even, as there wasn't a trail. Kinda disappointing, but if the design is without a trail, it would lead to fewer purchases in the case that there was a displayed image.
