This is a Tuesday puzzle. Shade in some cells of the grid so that all of the shaded cells are contiguous, every group of contiguous white cells touch the edge, and there are no 2×2 groups of shaded cells. In addition, the numbers on the outside represent the number of consecutive blocks of cells that they would see if they were instead buildings that high of cells, like a skyscraper. (So if a clue on the top of the grid saw VERTICAL segments of lengths 1,3,2,3,4 it would see the 1, the first 3 and the 4, and would be a 3)
Almost 2-3 rotationally symmetric. I had another version that was, but it sacrificed most of the fun logic.
