After looking at one of my invisible builds with my hammer out, I noticed how cool it looked, and so I decided to make more, and these are what I made:
The Matrix:
The 'Wall-O-Color':
A mini-city:
Mario :O
I hope that after you see these it inspires you to make some yourself, and if you do please post them here.
To create one yourself, wrench the bricks and uncheck rendering. Then take out any building tool, and viola! You can view yours!
