Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Fingerboard (skateboard)
A fingerboard is a working replica (about 1:8 scaled) of a skateboard that a person "rides" by replicating skateboarding maneuvers with their fingers, invented by Cameron Fox Bryant. The device itself is a scaled-down skateboard complete with graphics, trucks and moving wheels. A fingerboard is commonly about 100 millimeters long, and can have a variety of widths ranging from 26 to 34 mm. Skateboarding tricks may be performed using fingers instead of feet. Tricks done on a fingerboard are inspired by tricks done on real skateboards. Pofessional skateboarder Lance Mountain is widely credited as making the first fingerboard, and his skit in Powell-Peralta's "Future Primitive" video brought fingerboarding to the skateboarders of the world in the mid-1980s. Around the same time, he wrote an article on how to make fingerboards in TransWorld SKATEboarding magazine.
