Online Orrery Screen Capture

How awesome is this online orrery? Embedded in the black background are small grey control switches. You can set the date, display the zodiac, or trace a particular planet on the upper right. The slide on the upper changes the direction and speed of the rotation. I’m particularly enamored with the Tychonian universe option on the lower right and the lunar phase option on the lower left.
