Three Changes
Three Changes is an observation exercise in which partners face each other, study their appearance, turn away, and each make three small changes. They then turn back and attempt to identify what the other altered. The exercise sharpens observational detail and teaches performers to notice the subtle specifics that bring characters and environments to life.

Describe Me If You Can
Describe Me If You Can is an observation exercise in which players study a partner's appearance, then turn away and attempt to describe them in precise detail from memory. The exercise sharpens visual attention and reveals how much we overlook in familiar faces. It builds the observational skills that feed specific, grounded scene work.
What Has Changed
What Has Changed is an observation exercise in which partners face each other, study each other carefully, then turn away while one partner makes a subtle change to their appearance. When both turn back, the observer must identify what is different. The exercise sharpens visual attention to detail and the habit of specific, active observation of scene partners.
Camera Game
Camera Game is an observation exercise in which one player acts as a "camera," closing their eyes while a partner physically guides them through the space, briefly opening their eyes to capture mental snapshots of what they see. The exercise develops visual memory, trust, and sensory awareness. It reframes everyday environments as material worth noticing.
Imitate
Imitate is an observation exercise in which players study and reproduce the specific physical mannerisms, vocal patterns, and behavioral habits of another person in the group. The exercise sharpens observational detail and builds the ability to embody external characteristics with precision. Close observation reveals how much personality is communicated through small, habitual movements: the way someone shifts weight, the rhythm of their speech, the angle of their head when listening. Imitate develops the skill set needed for character work grounded in real-world observation rather than invention.
You Look You Seem
You Look You Seem is a character observation exercise in which players study their partners and offer observations beginning with "you look like someone who..." or "you seem like the kind of person who..." The exercise builds the skill of reading physical details as character clues and generates instant character material from observation.
Line Mirror
Line Mirror is a physical awareness and synchronization exercise in which participants stand in a line facing a partner line and mirror each other's movements simultaneously, without a designated leader. Unlike circle or pair mirror exercises, the line format creates additional complexity by requiring each participant to maintain synchronization with an immediate partner while also being observable by and influencing the rest of the line.
