What prevents me from supposing that this table either vanishes or alters its shape when no one is observing it and then when someone looks at it again changes back? But one feels like saying - who is going to suppose such a thing? (Ludwig Wittgenstein, On Certanity 1949-51) The film-maker accepts the challenge of the philosopher and changes not only a table but also chairs, shoes, jugs, teapots and almost everything else lying around his house.
