I have modified the pinwheel effect so it looks as expected for Lilia's sequence (it will always make sure there is a visible line now even if the thickness is smaller than a pixel
I tried this on .56 and its a little different than .55 but still pretty far off from .54 (see pics). This may not be evident in other pinwheel effects, but it turns out this "Lilia cross" effect in .54 got the most "oooohs" and "aaaahs" from my visitors so I finished out the year by staying at .54 and will need to figure out how to redo the "Lilia cross" for next year
