  Soft-matter systems when driven out-of-equilibrium often give rise to
structures that usually lie in-between the macroscopic scale of the material
and microscopic scale of its constituents. In this paper we review three such
systems, the two-dimensional square-lattice Ising model, the Kuramoto model and
the Rayleigh-B\'enard convection system which when driven out-of-equilibrium
give rise to emergent spatio-temporal order through self-organization. A common
feature of these systems is that the entities that self-organize are coupled to
one another in some way, either through local interactions or through a
continuous media. Therefore, the general nature of non-equilibrium fluctuations
of the intrinsic variables in these systems are found to follow similar trends
as order emerges. Through this paper, we attempt to find connections between
these systems, and systems in general which give rise to emergent order when
driven out-of-equilibrium.
