In 2013 the Nominet Trust launched the Social Tech Guide. The aim of the guide is to promote and celebrate inspiring uses of technology for social good. Each year they publish the Nominet Trust 100, a guide to the 100 best digital technologies for social innovation. The 2015 guide has just been published and features a wide variety of technologies, from Flowy, a game to help people combat panic attacks, to MOM, an inflatable incubator for use with premature babies in the developing world, to WREX, a robotic exoskeleton to help children with neuromuscular diseases.
