object floating above hand
Something floating above a character's hand(s); can either be something intangible, such as an orb, heart or a star symbol, in which a character might be casting a spell - or it might be a physical object, in which it might occur due to telekinesis.
A character might be cupping one or both hands. The object might also be glowing.
The object may also simply be falling, e.g., such as with a coin flip.
