Zusammenfassung: | A drawing device with a rotatable display screen is provided, having a housing having a cavity therein and a display screen sealingly rotatably coupled to the housing. An inner surface of the display screen forms an enclosure with the cavity. A powder is contained within the enclosure, the powder being removably adherent to the inner surface of the display screen. A first stylus controller is supported on an exterior of the housing. At least one positioning structure is supported in the enclosure and coupled to the first stylus controller to move a first stylus in a first set of directions that are parallel to a first axis. The first stylus removes the powder from the inner surface of the display screen through contact with the inner surface of the display screen. |
