Spectra started with the ambition to build a city for over a million people mixing the best of traditional urbanism and people-powered placemaking with 21st century tools and technologies. To work towards this north star and other undiscovered potential, Spectra Studios LLC launched the Spectra Cities community as a destination for physical placemakers and digital worldbuilders to come together and reimagine citymaking. We hope the community will become not just an incubator for a single project to build a city like Spectra in real life, but an open source platform for citymaking projects of all sizes. Spectra Cities also aspires to help train and educate the next generation of mixed reality citymakers and cocreate transformative, immersive experiences and events that help us have new, more empowering conversations about the future.
