§9.11. Clocks and Scientific Instruments

The simplest form of clock is a wrist watch. Here is a choice of analogue or digital:

The player wears a wrist watch. The description of the wrist watch is "It is [the time of day in words]."

The player wears a digital watch. The description of the digital watch is "It is [the time of day]."

Better clocks would allow us also to set the time, and to stop and start them: see Tom's Midnight Garden.

Scientific instruments provide sharper versions of our own senses. In the case of vision, they allow us to see closer up, or further away. It's a convention of IF that people can normally see only the current location, that is, they cannot see from one location into another. The boundary of the current room is like a horizon, even out of doors (though it's true that there are ways to disguise that with a continuous outdoor landscape). Ginger Beer provides a telescope able to see into other rooms.

Witnessed 2 provides a meter which measures how close a ghost is to the player.

*ExampleWitnessed 2
A piece of ghost-hunting equipment that responds depending on whether or not the meter is on and a ghost is visible or touchable from the current location.

*ExampleTom's Midnight Garden
A clock kind that can be set to any time using "the time understood"; may be turned on and off; and will advance itself only when running. Time on the face is also reported differently depending on whether the clock is analog or digital.

**ExampleGinger Beer
A portable magic telescope which allows the player to view items in another room of his choice.
