Some people got pretty deep into this shit. You can pretty much do most flip and grind tricks on a fingerboard that you can on a real board, barring those that have so many rotations that your wrist can't keep up. Learning tricks on it could actually parallel real trick learning too, since you needed to know the same principles, ie, where to pop/scoop, what each foot needs to do, etc.
It was pretty wild back in the late 90s-early 2000s, there were actually sponsorships for this and you could get flown around the world to do demos.
