It looks like trouble is brewing... the infection from two days ago has spread to this hapless rectangular grid and dotted it with spots! It's a deadly disease whose only cure is to build a diagonal village on top of the grid to contain the spread. Without further ado, here is the Penta Touch (or, given this shape bank,Touching Tetrominoes if you prefer) for you to treat!

Rules: Place each shape from the bank given outside the grid into the grid so that no shapes touch one another orthogonally. Rotating and reflecting shapes is allowed. Every grid point on which two shapes touch diagonally is marked with a dot.

Note: Pay careful notice to the "negative constraint" - two shapes can only touch where there is a dot! E.g. for the example, this is what makes the placement of the O tetromino unique.

A reminder that this puzzle uses the double tetromino set, not the pentomino set!
