As a tip, we had all kinds of problems trying to get it to work with Ubuntu Mate 16.04.1. We switched to Linux Mint, 18 "Sarah" using the Cinnamon desktop, and things went smoothly.
Under Ubuntu Mate 16.04.1, the Kinnect wasn't detecting at all.
We also had to switch out from a donated 15-pin VGA type projector to a new HDMI-inout projector to get control of the projected geometry. Our computer only has HDMI and DVI out, so I was running the HDMI cable into a converter to turn it into a VGA signal, and for some reason the projector assumed I wanted to show everything in 16:9, even if the image was a 4:3 1024 x 768 image (native for the projector). Once I hooked it up to a new Epson PowerLite 1761W projector, I was able to line things up again. The 1760 isn't officially a short throw projector, but it's going to work with about 40-45 inches (1.14 m) of clearance above the bed of the sandbox, which we can live with.
If it matters, I'm using this PC: http://www.memoryexpress.com/Products/MX60768
A Nightblade MI2-005TW with a Core i7-6700, 8GB, 1TB + 128GB SSD, and a GeForce GTX 970. It comes with Windows 10,. I added a SSD drive in the available little drive bay, and put Linux Mint there (since eventually the PC will go home with me, and be my X-Plane rig, and Blender Render farm box).
