Any computer program could be performed with pencil and paper This ruling requires that doing it my hand or purely mentally be achievable as a practical matter. It is not practical for me to draw frame by frame the contents of an AVI file by hand, even if it were theoretically possible, etc. While this ruling does leave judgment calls and grey areas, there are also a lot of cases where it can be decided very directly whether or not it is practical to do the operation by hand.
