Animation on the log in screen

This is animation on the log in screen of the Meeteor iOS app (app for meetings). Meeteor theme is space-related, with an astronaut as the main character leading you through the product. So the idea behind this spaceship hatch animation on the login screen is to create a feeling as if the user is entering another space, the Meeteor space.

The gif is a bit blurry due to dribbble required resizing.
