Abstract: An entertainment accessory device for use with an electronic device's built-in light source for projecting light effects onto a surface, such as onto a ceiling, wall or car interior. The entertainment device can operate in conjunction with application software loaded into a smartphone's computer memory that fluctuates the light emitted by the smartphone in reaction to the volume, frequency, or pitch of music played through or detected by either the smartphone or an independent audio source. The entertainment device can include multiple projection members than can be set to multiple configurations to alter the light effects.
