20$ PayPal for a single view, simple animation effect.

[Conquistadore]

Hello,

I am looking for a single view which has the following requirements:

1. There shall be 4 (four) 50x50 px marbles or balls by default. (You may use any image with the correct size.)

2. Two of them shall stay at the top and the other two at the bottom. Their centers shall be vertically aligned.

3. There shall be 100 px space between the upper and the lower two.

4. User shall be allowed to move only the second marble from the top.

5. Marbles shall move on the vertical axis only.

6. User shall be able to control the marble with a finger.

7. If marble2 collides with marble1, marble2 shall stop.

8. If marble2 collides with marble3, marble2, 3 and 4 shall move down. Marble 4 shall be out, marble3 shall move to marble4's previous location and marble2 shall stay at marble3's previous location. At the same time, a new marble shall appear at the marble1's previous location. Marbles shall slide down with animation.

9. The view shall be able to run in a tab view controller and a navigation controller. The view will replace a view in an existing application, so the objects shall adjust their positions accordingly.

If you have any questions, please don't hesitate to ask.

Thanks in advance.
