Claim 0:
1. A shutter system comprising:
an electronic device having a camera with a lens;
a shutter supported by the electronic device to block light transmission through the lens in a first state and permit light transmission in a second state, the shutter comprising:
a shutter body containing electrically charged light blocking particles in suspension;
a first pair of electrodes positioned to move the electrically charged light blocking particles to achieve the first state in response to a first voltage being applied to the first pair of electrodes; and
a second pair of electrodes positioned to move the electrically charged light blocking particles to achieve the second state in response to a second voltage being applied to the second pair of electrodes; and

an indicator body supported by the electronic device, the indicator body comprising a third pair of electrodes responsive to a third voltage to cause the indicator body to reflect a first color in response to the shutter being in the first state and a second color in response to the shutter being in the second state.
