Canvas swag bags are par for the course these days, but PopTech upped the ante yesterday by giving conference attendees the Swag Bag to End All Swag Bags: a Timbuk2 messenger bag that’s really a portable, solar-powered lantern in disguise. Built in collaboration with the Portable Light Project, the FLAP—Flexible Light and Power—incorporates solar panels that can be charged by day, and then used to power a built-in LED light or a cell phone/iPod at night.
