1. An air freshener device, comprising: a) a housing having a scent capsule aperture in a bottom thereof;b) a clip coupled to the housing forming a gap between the clip and the housing capable of receiving an automobile visor therebetween through a clip opening;c) an air displacement mechanism carried by the housing including a fan rotatably disposed in a fan cavity having an inlet and an outlet, a motor coupled to the fan to rotate the fan, a battery coupled to the motor to power the motor, and a switch coupled between the motor and the battery to selectively activate and deactivate the air displacement mechanism;d) a scent capsule carried by the housing and having a vessel enclosed by a permeable membrane and containing a fragrant material in the vessel that can permeate through the permeable membrane over time, the permeable membrane located adjacent the fan;e) the vessel having an inverted transparent dome forming a bowl;g) the bowl extending into the scent capsule aperture of the housing; andh) a light source disposed in the housing and coupled to the battery and switch, and located to emit light through the fragrant material and the bowl. 2. A device in accordance with claim 1, wherein the housing has a body with a cavity therein and a cover removably engaging the body and covering the cavity, the body providing four sides and the cover providing two sides including the bottom opposite the clip and a front opposite the clip opening, with an inlet aperture in the housing and a front outlet vent aperture in the front; wherein the housing has an air flow path defined through the housing in through the inlet aperture, past the permeable membrane of the scent capsule, and out of the front outlet vent aperture. 3. A device in accordance with claim 2, further comprising: a movable button movably carried by the front of the cover and located adjacent to and engageable with the switch of the air displacement mechanism, and the button being at least translucent. 4. A device in accordance with claim 2, wherein the scent capsule is carried by the cover; and wherein the cover includes the scent capsule aperture, the scent capsule further including a perimeter flange circumscribing the dome with a size greater than the scent capsule aperture to retain the scent capsule. 5. A device in accordance with claim 1, further comprising: a timer circuit coupled to the switch to deactivate the fan after a predetermined amount of time. 6. A device in accordance with claim 1, wherein the switch is a push button switch where sequential pushing sequentially activates and deactivates the fan. 7. A device in accordance with claim 1, wherein an axis of the fan is oriented perpendicularly to the permeable membrane of the scent capsule. 8. A device in accordance with claim 1, wherein the inlet of the fan cavity is adjacent to the permeable membrane and the membrane is narrower than the inlet to form at least one gap between the permeable membrane and the inlet. 9. A device in accordance with claim 1, wherein the scent capsule further comprises: two scent capsules disposed adjacent one another and each containing a different fragrance. 10. A device in accordance with claim 9, further comprising: a retainer plate removably securing the two scent capsules to the housing, the retainer plate having a pair of apertures corresponding to the membranes of the two scent capsules. 11. An air freshener device in combination with a visor of a vehicle, the device comprising: a) a housing having a body with a cavity therein and a cover removably engaging the body and covering the cavity, the body providing four sides and the cover providing two sides including a bottom and a front with an inlet aperture in the housing and a front outlet vent aperture in the front;b) a flexible and resilient clip coupled to the body opposite the bottom of the body and forming a gap between the clip and body receiving the visor therebetween through a clip opening opposite the front of the cover;c) an air displacement mechanism carried by the body of the housing including a fan rotatably disposed in a fan cavity having an inlet and an outlet, a motor coupled to the fan to rotate the fan, a battery coupled to the motor to power the motor, and a switch coupled between the motor and the battery to selectively activate and deactivate the air displacement mechanism;d) the cover having a recess and a scent capsule aperture;e) a scent capsule removably carried by the cover of the housing and having a vessel formed by a clear dome enclosed by a substantially flat permeable membrane and containing a fragrant material that can permeate through the permeable membrane over time, the permeable membrane located adjacent the fan;f) an air flow path defined through the housing in through the inlet aperture, past the permeable membrane of the scent capsule, and out of the front outlet vent aperture;g) a light source coupled to the battery and the switch;h) the clear dome being inverted to face downwardly and form a bowl received in the recess of the cover;i) the bowl extending into the scent capsule aperture; andj) the light source being located to emit light through the fragrant material and the bowl. 12. A device in accordance with claim 11, further comprising: a timer circuit coupled to the switch to deactivate the fan after a predetermined amount of time. 13. A device in accordance with claim 11, wherein the switch is a push button switch where sequential pushing sequentially activates and deactivates the fan. 14. A device in accordance with claim 11, wherein an axis of the fan is oriented perpendicularly to the substantially flat permeable membrane of the scent capsule. 15. A device in accordance with claim 11, wherein the fragrant material is a liquid contained within the vessel with the permeable membrane facing upwardly towards the clip. 16. A device in accordance with claim 11, wherein the inlet of the fan cavity is adjacent to the permeable membrane and the membrane is narrower than the inlet to form at least one gap between the permeable membrane and the inlet. 17. A device in accordance with claim 11, wherein the scent capsule further comprises: two scent capsules disposed adjacent one another and each containing a different fragrance. 18. A device in accordance with claim 17, further comprising: a retainer plate removably securing the two scent capsules to the cover, the retainer plate having a pair of apertures corresponding to the substantially flat permeable membranes of the two scent capsules. 19. An air freshener device, comprising: a) a housing with an inlet aperture and a front outlet vent aperture in the front and a scent capsule aperture in a bottom of the housing;b) a clip coupled to the body forming a gap between the clip and body capable of receiving an automobile visor therebetween through a clip opening opposite the front of the cover;c) an air displacement mechanism carried by the body of the housing including a fan rotatably disposed in a fan cavity having an inlet and an outlet, a motor coupled to the fan to rotate the fan, a battery coupled to the motor to power the motor, and a switch coupled between the motor and the battery to selectively activate and deactivate the air displacement mechanism;d) at least one scent capsule removably carried by the housing and having a transparent plastic sheet with an indentation on one side forming a vessel containing a fragrant liquid and covered by a substantially flat permeable membrane through which a fragrance of the fragrant liquid can permeate over time, the permeable membrane located adjacent the fan, and the indentation forming a transparent dome on the other side of the sheet from the vessel; ande) the dome with the fragrant liquid therein protruding into the scent capsule aperture in the housing. 20. A device in accordance with claim 19, wherein the at least one scent capsule further comprises: two scent capsules disposed adjacent one another and each containing a different fragrance; and further comprising a retainer plate removably securing the two scent capsules to the housing, the retainer plate having a pair of apertures corresponding to the membranes of the two scent capsules. 21. A device in accordance with claim 1, wherein the vessel comprises a transparent plastic sheet with an indentation on one side forming the vessel containing the fragrant liquid covered by the permeable membrane, and the indentation forming a transparent dome on the other side of the sheet from the vessel. 22.
