what:


The iBallDome is an 18 meter diameter, 9 meter tall inflatable dome. It is completely portable and can be set up iballdome-structure-smallwith minimal effort. The iBD has a single skin held up by air pressure differential, so its walls are flat and smooth to allow for seamless image projection. Think of a portable planetarium, with none of the disadvantages, like fixed location and fixed seating.
