Okay well I must've been high when I wrote this because the formatting is pretty weird.
Anyways I was thinking of a way to retain the style in which brick houses are layed, while not having astronomical brick counts. I came up with 2 solutions.

A print that will work to give the illusion of the desired effect. This gets hairy when dealing with the edges of walls though.
Then I came up with this idea:

These would just be whole bricks.
Anyone have any insight as to if this would cut down on lag?
