I'll try to make the explanation as simple as possible - a way to set a detailed description of a specific brick.
Let's say it's an event, self > setDescription, and it's parameters were the description itself, and the radius in whatever measurement you have to been in order to be able to "see" the brick.
Hypothetical situation, you want to set it up so saying /inv would spit out the description of each brick within a 60 stud radius. One specific tree brick's description is "an oak tree with dying leaves", so it would say in your client's chat "You see an oak with dying leaves".
Long story short, I'd love an easy way to set up a way to give the world some flavor text without being intrusive. I know this is possible, I just don't know how to do it :z
