Graduates from the California Institute of Arts made great use of office waste materials for their mini-planetarium which was glued together using a rice paste.

Dubbed the Reclamation Project, the mini-planetarium shows a starry night sky in a white papered dome.

The authentic rendering was recreated by pricking pinholes into a black paper cylinder. The inventors, Drew Denny and Kyoung Kim painstakingly folded 6000 sheets of trashed paper into quited sections covering the dome's reclaimed PVC pipe structure inside and out. The paper sheets were then assembled with homemade rice paste, which they used instead of toxic glues.
