Aha! You never set a position to the camera. The camera exist, and it is somewhere, and it's looking at your model, but it's not close enough to view it! Use Camera.setPos(x,y,z) to set the position. Also do some tinkering with the scaling to figure out a good scale for the model.

Turns out the texture is set on top of the cube, so you're going to have to rotate it a different way. Also, you *can* say "cube" or "sphere" for set geometry. My bad.

Also, after rotating the cube around different ways, The texture doesn't seem to appear properly, just the background color (offline, just grey). But if you set it to a sphere, you can actually see the texture.
