A planar point set S is an (i, t) set of ghost chimneys if there exist lines H_0, H_1,…,H_<t-1> such that the orthogonal projection of S onto H_j consists of exactly i + j distinct points. We give upper and lower bounds on the maximum value of t in an (i, t) set of ghost chimneys, showing that it is linear in i.
