-So, while I was scripting my Checkers board I had to incorporate an algorithm for arranging the pieces in a zig-zag pattern. As many of you already (but for those that don't, here you are), a checkers board is much like Quadrant-1 in a coordinate plane system. Which means in order to create this zig-zag effect, one has to construct as sequence like so: (0, 0), (1, 1), (2, 0), (3, 1), etc. And instead of using static, or hardcoded, values, I created a script that creates this sequence for me. Brace yourself, there is Trigonometry involved.

-This is just a simple for loop with text so you get the idea.

-Loop(integer max) {
-    list sequence;
-    integer x;
-    for(x = 0;x <= max; ++x) {
-        integer y = llCeil(llSin((x+1) * PI));
-        sequence += llList2CSV([x,y]);
-        sequence += "\n";
-    }
-    llSetText((string) sequence, <1,1,1>, 1);
