What, I'm the first one to post about it? I haven't looked at all of it. The first few new symbols are easy -- s is less than, t is greater than (possibly <= and >=?) * KP * PK * means the outer arguments are not equal to the inner ones (KP means "not" "equal", literally.) But the big bonus is o, which is a raster operator, where you take the binary sequence and spiral outwards from the center point on a hex grid! They draw the first few numerals for us -- 0 is a dot, 1 is a small hexagon, 2 is a large hexagon -- and then there's some bigger things I haven't translated yet. More when I do...
