ReDD is a remote drawing duplication effect which can be performed over a voice phone call, video call, virtual show and also, of course, in face to face performing situations. ReDD also qualifies as a propless effect as there are no props used and both the performer and the participant are only ‘interacting’ with each other, either over a call or face to face. A piece of paper which may be used to jot down a choice is just incidental and is not necessary.
