Back in March, we asked you to send us your best idea for a gadget, app, service or some other slice of tech genius for the chance to win a week's worth of mentoring by Google's experts in our Stuff Launchpad competition.
Hundreds of you submitted ideas that were everything from completely brilliant to completely insane (many thanks to the guy with the electronic spoon, you nearly made it), and after hours of deliberation we picked six favourites to pitch their ideas to our judges - Russell Hall, co-founder of taxi app Hailo, Oleg Fomenko, co-founder of Bloom.fm, Niko Schröer, Google Office Hours mentor and Simon Osborne-Walker, editor of Stuff magazine - at Campus London.
Here's the second, Adrian Cheang, with an idea informed by his own experience of training as a doctor. Frustrated by the huge amount of reading he had to do as a medical student, Adrian has designed an app that simulates just what doctors experience in real hospitals, allowing medical students to practice diagnosis in a gamified situation.
Watch the first Launchpad pitch, from David Kamailo, over here, and come back tomorrow to hear another brilliant idea!
