As usual, when stuck for ideas, I wander around related challenges... great excuse, as I do not always have the time to check them when they are just launched. Fantastic examples everyone.
@Richard thanks for the tutorial on the phone picture.
@David - wouldn't it be great if people also shared how they were inspired by challenge entries to create courses themselves?
I'm going to use the picture navigation idea to accompany a Health and Safety course. Part of it includes spotting hazards (inspired by the ice rink example, also in this challenge...).
When people spot a hazard on the screen, they can take a picture of it - then I can give them a recap at the end outlining all possible hazards they encountered - so they now know the frequent ones to look out for.
