Beautiful app – Orrery Review

I'm so glad the price was set low enough to just jump in for my five year old. How easy to explain days, months (lunar), and years plus seasons. There's just so much good about it. This is real craftsmanship! One thing I'm not sure I understand is the apparent precession of the earth. I suspect its axis should remain constant with respect to the starfield. Ah, one other thing is the earth's axis of rotation isn't colinear with the metal shaft it's mounted on. Some text explaining navigation wouldn't be bad. I love the Oort Cloud. Excellent!
