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.
