Endless Truckin'
Take a peek and pass it on, all of these trucks are the same on the inside. This is actually a picture of a truck manufacturing facility. Every truck is parked the exact same way by a robot, not a person, so it makes sense that they are all well placed.
Square Waves
This very seldom happens in nature, but it is not completely impossible to have square wave patterns. This happens when volcanic patterns underneath the waves start interrupting the surface. By proxy, flat bodies of water can exhibit a gridded pattern that corresponds with the wavelength of the vibrations coming from underground.
