X-Space, a library built and designed by its students features Stax, a building unit used to create the library. The X-shaped unit made out of wood that can be connected to create a large bookcase or even used as a structural unit to make chairs or benches. The campaign is really raising money to build their library X-Space, but backers are able to buy Stax units for themselves. Early backers can receive one Stax unit for $149 or at the regular price of $199. X-Space is hoping to raise $75,000 in its 30-day campaign on Kickstarter.
