  Although crystallization is a ubiquitous phenomenon in nature, crystal
formation and melting still remain fascinating processes with several open
questions yet to be addressed. In this work, we study the emergent
crystallization of a laser-driven dipolar Bose-Einstein condensate due to the
interplay between long-range magnetic and effectively infinite-range
light-induced interactions. The competition between these two interactions
results in a collective excitation spectrum with two roton minima that
introduce two different length scales at which crystalline order can emerge. In
addition to the formation of regular crystals with simple periodic patterns due
to the softening of one of the rotons, we find that both rotons can also soften
simultaneously, resulting in the formation of exotic, complex periodic or
aperiodic density patterns. We also demonstrate dynamic state-preparation
schemes for achieving all the found crystalline ground states for
experimentally relevant and feasible parameter regimes
