You can expect 300 hours (but this varies). The Projector is the heart of a Multi-Sensory Environment: Casting gently moving images and patterns onto the walls, floor and anyone in the way. Projection Curtains double the impact of the projector, as the image is projected both on and through the sheer material. Projection Curtains allow you to actually touch the images without casting a shadow. Create a relaxing, almost fluid space, completely surrounded by light. Add a fan to stimulate the curtains, or a Panoramic rotator to send the images flowing around the room, and you have created an environment in which the normal rules have changed. Different behaviours will be exhibited; what can you make of them? Both Projectors can be secured to a shelf or to the ceiling by a swivel point that allows the image to be moved while holding the projector safely in one place.
