Too much intelligent discussion on here of late, so here's a film about balls to counterbalance it.
In all seriousness, thanks for all of your thoughts and comments over the past few days, it's great to have some healthy discussion, so please do continue to share your thoughts.
This brilliantly simple film was made by the extremely talented Daniel Mercadante, using images found using Google image search.
Also by Daniel is this superb film Laughs, made completely using clips found on the web. Try to watch it and not laugh.
