We review the Coset Space Dimensional Reduction (CSDR) scheme and thebest model constructed so far. Then we present some details of an alternative CSDRprogramme, in which the extra dimensions are considered to be fuzzy. Specifically,we present a four-dimensional N = 4 SYM theory, orbifolded by Z3, which mimicsthe behaviour of a dimensionally reduced N = 1, ten-dimensional gauge theory overa set of fuzzy spheres at intermediate high scales. This leads to the trinification GUTSU(3)3 at slightly lower, which in turn can be spontaneously broken to the MSSM inlow scales.
