Drawing with Rectangles - Robots, Trees, and More Posted on June 26, 2013 by Rob Stenzinger This is a series of experiments in using rectangles to draw a few things both natural and human-made. One technique I found useful through this was to work loosely and not focus on perfect symmetry. These three robots began my curiosity with rectangle based drawing. Buildings, perhaps to use in a future video game concept. Exploring how I could draw trees using only rectangles. An attempt at clouds, though they more closely resemble battleships or extra simplified 8-bit art. It's rectangles all the way down and I think it warded into taking a little break from the rectangle sketching.
