Thanks Nan. I’ve added #3 for now as well, and improved things a little
for spherical puzzles. The twists will now animate, and I corrected the
twisting of inverted slices. If you saved your {5,3} FEV solution file, it
may be broken (depending on whether you used that inverted twist when
solving). Sorry about that.
