LITS puzzle

LITS is a Nikoli logic puzzle type. A grid is initially divided into several heavily outlined regions. Within each grid you must blacken 4 squares forming one of the tetromino shapes L, I, T, or S such that no 2x2 grid section is completely blackened (thus, the O tetromino is not allowed), all the tetrominoes form one orthogonally connected group, and no two tetrominoes of the same type touch along an edge.
