I finally got around to uploading a video of some of my very early experiments.
This was one of the first things I did when I was learning Unity. One of the tutorial guys I was watching kept starting tons of videos with a black plane for a floor, a white cube as a "table" and a smaller cube sitting on it and colored.
So I built that. Then made the "table" bigger and added a couple more blocks. Then I copied the table and added colored spheres. Then I found a free car model, so I made a table for them. Then I found some other random assets to play with.
At some point I went through a hand animation tutorial, so I added those to this project. That was one of the most frustrating things I've done to date.
Now that I have a real mouse, I think it would be a lot easier. I was on my MacBook with the trackpad and that wasn't fun at all. It's hard to "scroll the mouse wheel" on a trackpad for example. For the curious, the frustration thing is the tutorial I went though started you with a basic hand. And you had to animate the rest. So when the trigger is pulled, you needed to move the index finger to the final position. When meant bending each joint until things looked right. Then repeat that with the grip button, but that one controls the other three fingers and I had to do each joint on each finger.
Later I came across a "how to make a gun shoot" video, and since I already had the guns, I added that in there. Then I made a few changes like a running score and bullseye-in-a-row. It's a silly gun, but that's what the tutorial had me build. 
I eventually stopped adding to this project and went on to work through lots of others. Teleporting. Building doors that can be opened. Buttons that can be pushed. Guns that shoot bullets instead of squirt guns. 
One thing I had started on before getting distracted by other things is the idea of a photo gallery. Upload a ton of photos to the headset, then have some space auto-generated displaying the photos as pictures on the wall. Then you could click on the photo to see it full sized. I think it would be cool to have a museum. One room could be photos / videos of one child. I could have another room for the other child. Another room for whatever. Just stick them in their own subfolder. I think that could be super nifty. I just need to get back to that. As I recall, I was reading the photos from the folder and displaying them pretty well. Next up I need to figure out how many photos are in the folder, and construct a room of the appropriate size and stick them on the walls. I'll get back to it eventually. Nothing worth showing at this point. Just a bunch of pictures hovering a few feet off the floor.
