A light source is attached to the body and illuminates selected characters. Control circuitry triggers the light source to illuminate the selected characters to display a message as the disc rotates. ## Claims ### Claim 1 A device, comprising: a body; a disc, rotatably attached to the body, that includes a plurality of characters arranged around the disc; a light source, attached to the body, that illuminates selected characters of the plurality of characters; and control circuitry configured to trigger the light source to illuminate the selected characters to display a message as the disc rotates, wherein the light source includes a plurality of light emitting diodes (LEDs) and the control circuitry triggers individual LEDs of the plurality of LEDs according to a position of a corresponding character within the message. ### Claim 2 (depends on 1) The device of claim 1, further comprising a handle, rotatably attached to the body, connected to the disc to cause the disc to rotate. ### Claim 3 (depends on 1) The device of claim 1, wherein the control circuitry is further configured to trigger a single LED of the plurality of light emitting diodes at different angular positions of the disc to visually superimpose multiple characters. ### Claim 4 (depends on 1) The device of claim 1, further comprising a position sensor that determines an angular position of the disc, wherein the control circuitry is further configured to trigger the light source according to the determined angular position of the disc. ### Claim 5 (depends on 4) The device of claim 4, wherein the position sensor includes a photosensor that detects a mark on the disc and wherein the control circuitry is further configured to determine the angular position of the disc based on a rotational speed of the disc and a time elapsed since the photosensor detected the mark. ### Claim 6 (depends on 5) The device of claim 5, wherein the control circuitry is further configured to determine rotational speed of the disc based on a period at which the mark is detected. ### Claim 7 (depends on 1) The device of claim 1, further comprising a motor connected to the body that causes the disc to rotate. ### Claim 8 (depends on 1) The device of claim 1, wherein the disc includes a translucent material and wherein the plurality of characters are opaque. ### Claim 9 A device, comprising: a body; a disc, rotatably attached to the body, that includes a plurality of characters arranged around the disc; a plurality of light emitting diodes (LEDs), attached to the body, that illuminate selected characters of the plurality of characters; a position sensor that determines an angular position of the disc; and control circuitry configured to trigger individual LEDs of the plurality of LEDs according to the determined angular position of the disc and a position of a corresponding character within a message to illuminate the selected characters to display the message as the disc rotates. ### Claim 10 (depends on 9) The device of claim 9, further comprising a handle, rotatably attached to the body, connected to the disc to cause the disc to rotate. ### Claim 11 (depends on 9) The device of claim 9, wherein the control circuitry is further configured to trigger a single LED of the plurality of light emitting diodes at different angular positions of the disc to visually superimpose multiple characters. ### Claim 12 (depends on 9) The device of claim 9, wherein the position sensor includes a photosensor that detects a mark on the disc and wherein the control circuitry is further configured to determine the angular position of the disc based on a rotational speed of the disc and a time elapsed since the photosensor detected the mark. ### Claim 13 (depends on 12) The device of claim 12, wherein the control circuitry is further configured to determine rotational speed of the disc based on a period at which the mark is detected. ### Claim 14 (depends on 9) The device of claim 9, further comprising a motor connected to the body that causes the disc to rotate. ### Claim 15 (depends on 9) The device of claim 9, wherein the disc includes a translucent material and wherein the plurality of characters are opaque. ### Claim 16 A device, comprising: a body; a translucent disc, rotatably attached to the body, that includes a plurality of opaque characters arranged around the disc; a handle that is rotatably attached to the body and that is connected to the disc to cause the disc to rotate; a plurality of light emitting diodes (LEDs), attached to the body, that illuminate selected characters of the plurality of characters; a photosensor that determines an angular position of the disc by detecting a mark on the disc; and control circuitry configured to trigger individual LEDs of the plurality of LEDs according to the determined angular position of the disc and a position of a corresponding character within a message to illuminate the selected characters to display the message as the disc rotates. ### Claim 17 (depends on 16) The device of claim 16, wherein the control circuitry is further configured to trigger a single LED of the plurality of light emitting diodes at different angular positions of the disc to visually superimpose multiple characters. ### Claim 18 (depends on 16) The device of claim 16, wherein the control circuitry is further configured to determine the angular position of the disc based on a rotational speed of the disc and a time elapsed since the photosensor detected the mark. ### Claim 19 A device, comprising: a body;
