I happened to find HiLo Challenge Domes a short while ago, and they fully deserve a mention as innovators of a product using a geodesic dome.
Simply put, HiLo specializes in challenge course domes, similar to those challenge courses we did at summer camp or in school, except for the fact that it all happens inside a dome. Here is a video overview below.
Even more interesting is how special attention is paid to safety and security aspects. This is a professional setup that has been conceived and engineered with, dare we say, vision. Conratularions to HiLo Domes, and for gorgeous images and information, visit http://hilochallengedomes.com/
