Did you ever notice the wheels on the car driving next to you sometimes appear to be spinning backwards? This is referred to as the stroboscopic (or wagon-wheel) effect. It occurs when an object is rotated at certain speeds, making the object to appear to stop or even go backwards. Rotate 4 different objects in either direction (clockwise or counterclockwise). You can increase the speed until you see it appear to stop or reverse. On one of the objects, a wheel with different colored alternating rings, you can make it appear as if the rings of this single option are turning in opposite directions. Universal App - supports native iPad, iPhone and iPhone 4's Retina display. WARNING - Those with Epilepsy or those subject to seizures are usually cautioned to avoid strobe lights or similar effects.

The screen at startup is the earth.The equatorial inclination angle of the earth is 23.4 degrees.Equatorial inclination angle is the angle between the equatorial plane and the orbital plane of a planet that revolves while rotating. The equatorial inclination angle of the mercury is 0.027 degrees.The rotation axis is upright almost vertically. The equatorial inclination angle of the venus is 177.36 degrees.The rotation axis is almost completely inverted, and it rotates in the opposite direction. The equatorial inclination angle of the mars is 25 degrees.The axis of rotation is a gradient close to the earth. You can change the rotation speed of the planet.The equatorial inclination angle of the jupiter is 3.08 degrees.The rotation axis is upright almost vertically. When you press the button, the angle of the sun changes by 30 degrees each time. The fastest thing is one revolution per second.The slowest thing is one rotation in 300 seconds (5 minutes). When checked, reverse rotation will occur.
