yum install perl-ExtUtils-MakeMaker perl-Term-Animation -y 

The above 2 packages are dependencies for this animation in terminal.

Then download ASCIIquarium from http://robobunny.com/projects/asciiquarium/asciiquarium.tar.gz

Decompress this tar and give it an executable permission (+x).

Copy it over to any location in your $PATH, in my case, I copied to ~/bin

Show the ASCIIquarium by typing asciiquarium

You can quit the animation by pressing “q”.

Another similar cool terminal animation is cmatrix, give it a go
