Some strik­ing nature-inspired gen­er­a­tive visu­al­iza­tions can be found over at Imi­tate and infor­mate. From the site:

This is an exper­i­men­tal visu­al­iza­tion project. We are inspired by nature or other real phe­nom­ena and try to trans­form for­mal aspects of it into data visu­al­iza­tion systems.

Imi­tate and Infor­mate is a project by Cedric Kiefer and Christo­pher Warnow. It emerged from a course called “Real­ity in Vir­tu­al­ity” at Pots­dam Uni­ver­sity of Applied Sci­ences, Prof. Dani­jela Djokic.
