Frame

A stylish item and node frame that causes no lag/server load.

This is an entity-free implementation of item frames. The upside is that there are no entities and therefore no special lua code needed to spawn item entities and clean them up. However, a downside is that items can't just be inserted randomly - there needs to be code added to mods that add nodes and items to allow inserting them into frames. For really busy servers this may be highly beneficial.
