The i3 Detroit, based in USA, Michigan, Ferndale, Wordsworth, is a meeting & (un)conference and a hacker space. It can inspire other space creators who want to boost exchange between diverse people, prototyping of products or services.

This group manages to maintain a serious complement of tools, rivaling some very expensive professional shops, while keeping much of the open free-wheeling attitude typical of hackerspaces, and really affordable dues. The secret is that everyone pitches in — there are no “customers” at i3detroit, everyone’s part-owner. The group is self-funded and volunteer-run, and pretty much any DIY/creative interest is welcome. Couches are always comfy, pop is always cheap, people are always up to something crazy, and the door is almost always open.
