In the mobile children’s exhibition Halfdans Univers, we interpreted selected poems from Halfdan Rasmussen’s popular ABC book as spatial interactive installations. Based on the ABC, we created four scenarios where children between the age of 4-7 can discover the imaginative and playfull universe of the poems and get acquainted with letters and rimes. Each installation is carefully build as assembly kits and will be touring different culture houses throughout Denmark. The exhibition has been developed in close collaboration with the scenography duo Sir Gran Lear.
