Lots I'd like to improve and add to this though and I would really appreciate some help.
Firstly I've been trying to automate the growth rather than using a mouse click.
How can I set-up a limited queue of events?
Fire periodically and Count within range does not seem to be working for that.
I've been reading and re-reading the manual on the subject but having trouble understanding Build lists, Queues, and Hold lists. (I always did have issues understanding Iterators in Qtz too, it's just an alien abstract mathematical thing my brain has issues with).
Second I'd like to add leaves or flowers to the structure and also make it a solid rather than line object, can't work that out either yet.
A little follow up info from Jesse.
Unfortunately Microsoft does not provide a Mac driver for their SDK and only libfreenect2 can be used on Macs.
On a mac you are unfortunately limited to the Kinect 1 joints. If you have access to a Windows PC you could try using NI mate on it.
