This uses a tile shape very similar to the hat, but the tiling _structure_ is totally changed so that there aren't any reflected copies of the tile. I'm not sure how much difference this makes to gameplay: the two tilings are very similar for Loopy purposes. But the code was fun to write, and I think the Spectre shape is noticeably prettier, so I'm adding this to the collection anyway. The test programs also generate a pile of SVG images used in the companion article on my website.
