Need to make an example of working in Iphone 4,4s, 5.
Cursor (circle) moves up and down on their own .. up and down, the user monitor it with your finger.
If the user does not have time for the cursor - an error.
See video example - web-studium.ru/tmp/20131218094547.MTS
Design is not needed, just functional.
Work must be submitted in the form of source code for Xcode 4.x
