  We simulate the transport of colloidal particles driven by a static and
homogeneous drift force, and subject to the optical potential created by two
lattices of optical tweezers. The lattices of optical tweezers are parallel to
each other, shifted, and rotated by a twist angle. Due to a negative
interference between the potential of the two lattices, flat channels appear in
the total optical potential. At specific twist angles, known as magic-angles,
the flat channels percolate the entire system and the colloidal particles can
then be transported using a weak external drift force. We characterize the
transport in both square and hexagonal lattices of twisted optical tweezers
