A fictional object that looks like a floating
cube,
pyramid, cylinder, etc. It can be used as a toy to watch a group of short videos. The point of the videos is to
try to guess the theme of them. It could be something like "the five fingers" or "the
five senses" or something like that. Graybles can also be used for emergencies. If you are in danger and you watch a grayble, it
will show you a way to get out of danger. It might show an event that happened to someone else in that same place and you can learn from their mistakes or their successes, but you never really know with a grayble. Graybles almost seem like they have a mind of their own.
