Finally checking in! I've only been working on this for a couple weeks, but here's the current state of my Jam submission:

LeapGarden is a world building sandbox, with a Japanese garden theme. It's a VR experience. Ever since the Leap was announced I've been excited about world building in VR using only my hands, and this Jam has been a great opportunity to play around with some of my thoughts.
So far I've implemented single object creation with basic transform manipulation (using two hands to indicate transform/rotate/scale). I've also implemented a "spray" feature for repeated objects like flowers. I'm using the two-hand movement scheme from the Leap samples (I've tried a couple other things but nothing has worked as well yet).
I'd still like to implement a select to further manipulate objects in the scene, and at least a one-level undo stack to correct errors. I'd also like to create an interesting terrain with a pond, but that may or may not happen this week!
Cheers, and thanks for giving us a great excuse to play around with this fun tech!
