An Infinite Knight's Tour
A classic chess problem is to find a sequence of moves for a knight to land on every square exactly once. With a knight initially positioned at the center of an infinite chess board, drag the slider to see a portion of an infinite knight's tour, either as a broken line path or by numbering the squares in order. You can change the size of the displayed portion of the board.
