Zzz-morphing-animation icon png download

This is the remix of " Reading activates your imagination" uploaded by "danzajicek". Thanks. This animation depicts a person who is sleeping while he pretends to read a book. The letter "z" in the thought bubble is morphing or scaling up and down , implemented by [attributeName="d"] function of SMIL. [NOTE] My SMIL animations do not work with "chrome". Though I want to fix it , I do not have any clue about fixing it for now.
