Thinkagrams are a means of long distance communication between two or more Units. The spell can be one-way or two-way. The spell is cast by the Caster, who does not need to tbe the target. A floating, visual image of the target appears before the recipient, allowing other Units in the vicinity to observe the effect. Anything spoken by the target is heard by the recipient and other observers. If the two-way version is cast, an image of the recipient is displayed to the target and anyone observing the casting: anything spoken by the recipient is also heard by the target and observers.
For the duration of the spell, the fingers of the Caster are held in a rectangle, index fingers to thumbs of opposite hand, as a Director or Photographer might in a TV show. The image of the recipient appears in front of this rectangle.
