Four designs using only five black squares

1: A square falling in a 'flipnote' style.

 2: Squares falling into a stacked pyramid.

 3: A formation of large squares moving in unison.                            

4: 4 squares pinning the 5th square into submission.

In this, I had to create 4 designs using only 5 black squares that would make the onlooker think about what it may be representing, if anything at all.
