Look carefully at the image above. Stare intently at the centre of the screen as though you were penetrating far beyond its shallow depth of however many centimetres.

If that’s the number you guessed, as Jimmy Stewart famously says at the end of It’s a Wonderful Life, ‘That’s right, that’s right’.
