A clever mod that takes most of the vanilla blocks and turns them into one-way windows. Transparent on one side, but opaque on the other, these glass blocks filter light, turning a wall that appears solid into a massive window that can be used to survey the land.
This mod also comes with glass tools. Simple to craft and essentially infinite, they're a good tool to have that also comes with the advantage of being invisible to anybody but the wielder. Alas, these tools are made of glass.
