Monday Mutant 80: Streampunk / Tetra Firma

Shade in tetrominoes such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. No two congruent tetrominoes may share an edge, even if they are rotated or reflected versions of each other. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 3" means the cell shares a corner with four black cells which form a group of three cells and a single separate cell. Cells with numbers cannot be black.
Fillomino-Fillia is over, and MellowMelon is hosting a contest where you can try guess the authorship of each of the 18 puzzles. Check it out!

Very interesting variant. It was fun figuring out how the constraints imposed by the LITS aspect forced uniqueness out of relatively open-looking regions (i.e. the center and top right).

Sort of shuddering to imagine what the theme contest ('LITS-omania!") would be like for that...
