Hi Mariya,

This was SO COOL, that I had to make something immediately.

In the rush to make something and the lack of equipment, I ignored all the great tips you gave in the preparation steps. :)

I hold the phone in my left hand in such a way that my thumb could press the "take picture button" I did set the Auto focus lock.

And tried to hold everything in place as good as I could.

Digitally I made only basic corrections, I imported all my frames using an auto align feature, and cropped the empty space. (there is some noticeable movement).
As It is a ceiling light, I used a simple adjustment layer to cool the temperature and increase the exposure a bit.

Attached a still frame and an Animated GIF
