What on earth do the directions mean, here?

Start moving right.
< Start moving left.
^ Start moving up.
v Start moving down.
? Start moving in a random cardinal direction.

What is moving in a direction? Is this supposed to simulate instruction pointer movement? Surely not. How exactly does an IP move "down"?

Jeez. This was a kata that really underlined the importance of Linq statements.

Wow this is an elegant solution. Good work.
