Hey there
@TomND nice to meet you
The Leap is definitely a fun little toy, doubly so if you have an Oculus to strap it to. I've got both and am sure I've looked like an idiot trying to pop floating bubbles in VR
In fairness it would be a tricky GSOC item especially not having a unit yet with proposals due in two weeks. Our original prototype implementation and minimal lib attempt is 2+ years old at this point and I might have been the only one to really touch the code (now woefully out of date). If you want a chance to qualify for GSOC (and the odds are poor I'm afraid - check our
main GSOC thread for details) you might want to look at one or more different items you can try to start examining right now.
Alternatively if you'd just like to break into game dev and play with something like the Leap whenever then we're here for that any time and I'd be happy to help guide and test there myself. I know there are some nice libraries out there for casting spells via gestures using the leap for instance and would love to see that work in Terasology one day
Edit: Oh and in any case please start by grabbing the source and making sure you can run the game that way. Then look around in our main GitHub repo for more doc and ideas and let us know if you have questions or would like more guidance
