The Commercial:
A driver is navigating late-afternoon traffic; the setting sun is directly in front of her.
She flips down the visor, but the sun's too low.
She scrunches and turns trying to block that little ball of sun with the rearview mirror, the car edge of the car frame, anything.
She can't and drives with one hand shielding her eyes.
Another car pulls out in front of her, she can't see well enough and reacts too late.
The driver, apparently unhurt, now stands next to her damaged front end, with a copper writing a ticket.
If only she had a Solar Eclipse.
A circular piece of cardboard about four inches in diameter, with a suction cup attached to one side, the Solar Eclipse is a simple yet innovative device. When the blinding, burning, or just annoying Mr. Sun comes blazing through your car window at an angle that your visors can't block, you pull the Solar Eclipse out of the glove box, lick the cup and paste it to your windshield or side window, blocking the offending light. The suction of the cup is not very strong allowing you to slide it across the glass as the car/sun angle changes. The Solar Eclipse would, of course, be decorative as well as different images would be printed on the cardboard. The selection of images would include a Moon (naturally), a Cloud, a Hand, a Giant Squashed Bug
