I've made a prototype of an educational navigation simulator. You have to steer a cargo ship into the dock at Southampton using a very small bit of a UK Hydrographic Office chart. It's harder in the fog like in the second screenshot. I made this at Taunton Coderdojo. It was an idea from the coders who volunteer at the Coderdojo and work at the Hydrographic Office in Taunton. It's been a rush to get the protoype ready for Coolest Projects in Manchester on 2 March.
I am doing lots of projects every projects all the time and I can't put them all on the website so I've made a blog.
