Claim 12:
13. A device comprising:
a shutter body containing electrically charged light blocking particles in a suspension fluid to block light transmission in a first state and permit light transmission in a second state;
a first pair of electrodes positioned to move the electrically charged light blocking particles laterally to achieve the first state in response to a first voltage being applied to the first pair of electrodes;
a second pair of electrodes positioned to move the electrically charged light blocking particles vertically within the shutter body to achieve the second state in response to a second voltage being applied to the second pair of electrodes; and
means for supporting the shutter body about a camera lens of an electronic device to
selectively block and permit light transmission through the camera lens; and
an indicator body supported by the device, the shutter body comprising a third pair of electrodes responsive to a third voltage to cause the shutter body to reflect a first color in response to the shutter body being in the first state and a second color in response to the shutter body being in the second state.
