Invisible bridge blocks

Invisible bridge blocks would be blocks that appear invisible from afar but glow in a colour as entities interact with them. I think this block would work well in a new end biome, and could add to interesting player interacitons. The block could be made visible by using spyglasses aswell, adding another use case to the item. They could generate in big panes in the end encouraging you to watch where ur going as you cant see more than 5 or so blocks ahead. Players could use this as an invisible barrier (from afar) as well as many other interesting uses (visualising arrow trajectories, fun floor to have, etc) i dont have a name for this block but i think a mineral type of name could go well.
