...rc starts at the rightmost point, and can be shifted around using a rotate transform.

Is recursion ever faster than looping?
...C compilers, one can use a compiler flag to eliminate this overhead, which transforms certain types of recursion (actually, certain types of tail calls) into jumps instead of function calls.

What is the difference between compile and link function in angularjs
...- by copying content from the instance scope into the DOM.
Note that DOM transformations can be done in the compile function and/or the link function.
