What are the best algorithms (and explanations) for representing and rotating the pieces of a tetris game? I always find the piece rotation and representation schemes confusing.
Most tetris games seem to use a naive "remake the array of blocks" at each rotation:

However, some use pre-built encoded numbers and bit shifting to represent each piece:

Is there a method to do this using mathematics (not sure that would work on a cell based board)?
