Yes. Props are used in mime not only for conveying messages, but also to set a specific mood to their story. For example, Mummenschanz shows a wide variety of props used to convey different emotions in their anecdote and made exaggerated movements with them to show a little bit of humor, as well as other feelings depicted also by the light, body positions, and space usage. :)
