Experimentation with the background

Using picture of space

some of the pictures I tried as well






Attempt to get stars on the background moving as well.
I know why this attempt failed. Because all the dots follow the mouse and then they all just stay right under the cursor overlapping each other, so they look as a one dot. But I jst didn't manage to figure out the way how to make them just chase the mouse all the time without going directly to the cursor and staying there.
