Hi,
I volunteer for our local CoderDojo in Manchester in the UK [1]. We have been given a space in the local library to run drop-in sessions for the Manchester Day Parade [2]. As part of that we are hacking together a Minetest parade. Kids will be able to build floats using Minetest and then put them together in a parade that will be projected on to the wall of the library. We've made some progress (with a week to go -- gulp). The code is up on github and any feedback and pull-requests would be much appreciated.
