creeping things

"Our usual movement is concentrated: a force is applied to one end, and the other end changes its position passively under its influence. This is a lever-like movement. However, the deeper and more fundamental aspect of this movement is the oscillating motion of life, where there is no distinction between active and passive elements, and everything is equally important. This movement, which flows throughout the body, is referred to as peristalsis, convulsions, spasms, the movement of flagella or legs, pulsation, and various types of crawling. However, the essence of this movement is its lack of division into periods (steps) and the absence of a center of thrust. This is what makes reptiles so repulsive. After all, the movement of a snake is the movement of a gut, and the shape is the same."
- Leonid Lipavsky, "The Study of Horror" The composition conveys the feeling of unconcentrated movement. The absence of a center of thrust is a characteristic of many creeping things.
