Those forward tumble thingies are awesome looking. What are those called? (where it looks like the nose falls over and loops tight)

From watching a few Bipe videos now I defintely see that they land faster (with power). One other thing I notice is that on the take off they look like they almost tip over to one side before wheels up. Do I have that right?

Also, what is the trick for the confusion on the orientation?

Thanks
