The aim of bachelor thesis was to create a popular-educational book about clouds. Visuality of clouds is their undetachable part. That’s why the focus of my book is graphic illustrations. Through illustrations I was able to analyze their patterns. Lines that create every cloud are also acting as visual moare, trembling in front of the eye, apearing intouchable. Exactly as clouds. Important part of the book is also its information level, consisting of categorization of clouds into species as well as height levels.
