Prism UI

Beautiful, modern interfaces for Garry's Mod.

Prism gives Garry's Mod the kind of polished, smooth-feeling UI you'd expect from a modern game. Menus glide into place, panels blur the world behind them, and text stays crisp at any size. It all runs right alongside the menus, chat and console you already know.
