Use this thread as an opportunity to post shots where the effects of spin (crazy side-spin, top-spin, back-spin, whatever) are clearly noticeable causing a visible bend in the flight of the ball.
Obviously there is Nadal's classic banana shot at 0.25;
But this thread isn't limited to banana shots, i.e. check out Bellucci's forehand at 3.28;
That's got some weird topspin/outside side-spin combination on it.
Wind-altered shots are cool too.
