Combinatorial discrepancy deals with the following question. Given a collection of vectors or matrices A_i, determine -1 or +1 signs s_i such that some suitable norm of the signed sum  \sum_i s_i A_i  is as small as possible. I will briefly survey some recent techniques that have been developed to address such problems and describe some open problems in the area.
