Flicker star

I created something like a flickering star to show
There is something to interact with, It's blinking!
You can see structure of the motion in this GIF

we must guide our users,
Help them to understand what to do or where to go,
Sometimes we can do it with a small motion like this and sometimes you have to tell them directly
"click here!"

It happens many times when we design a user interface and we think they should understand this. It's obvious! But after some usability tests, we can find they couldn't get it!
