Hello Borate
First of all, thank you for your time!
My idea has 2 elements: the calendar is fixed at the bottom of the screen; the clip (bird) appears in small size superimposed in a box of the calendar to then grow and occupy the entire screen. I put an archive of the elements on this link https://www.dropbox.com/s/7zf4evdtpldq0vf/Archive.zip?dl=0 because I didn't find how to attach to my answer.
