Rules
- Divide the grid into ominoes (regions of orthogonally connected cells), so that no two ominoes of the same size share an edge. Each cell contains a number equal to its omino's size.
- Shade some cells so that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 is fully shaded or unshaded.
- An arrow in a cell indicates that the omino pointed to by the arrow contains N shaded cells, where N is the number in the arrow's cell. An arrow may be in the same omino as the cell it points to.
Solution code: The cell values in row 8 (without separators).

Simply fantastic! I feel like it took me way too long to understand some of the key logic required, but it was really cool once I figured out how things worked!

I was expecting a coral, but I'll take a fun and smooth yin yang hybrid like this any day, of course :D
