An idea to link up a photo booth with social media gave birth to Photoboxx, a Spokane Valley business that sets up at events to give away prints of photos snapped by Instagram users. Just over a year ago, Michael Fisk and Devon Lind worked to build the technology behind a photo-printing station that Photoboxx now installs at public events, where people gathered for fun activities are prone to take photos with their cellphones. When Instagram users post their snapshots with a designated event hashtag, they get a free Polaroid-style photo that prints from the company’s booth.
