"Geometry Playground" Exhibit (Image 9)

June 26, 2012
These tessallating stellated rhombic dodecahedrons are part of the "Space-filling Blocks" activity at the Exploratorium's "Geometry Playground" exhibit. Visitors are encouraged to stack the dodecahedrons so there is no wasted space. Filling up space completely with almost no gaps in between is called tessellation. The space-filling blocks activity let's visitors experiment with which shapes tessellate and which don't and the orientation of the stacking required. Developed by the San Francisco Exploratorium, "Geometry Playground" is a fully interactive exhibition that includes over twenty exhibits and specially commissioned artworks. With "Geometry Playground," visitors use their hands, their bodies and their minds to explore what for most has been only a textbook subject. The exhibition was funded by the National Science Foundation (grant DRL 06-10436) and the Gordon and Betty Moore Foundation. Further information about the exhibit is available Here.
