Basically, you custom-build the teeniest skateboard imaginable & then use your fingers to do flips, stunts & tricks with it. Some people seem to take it VERY seriously & indeed our caller bought some very high-spec Japanese miniature bearings for his board, as he wants to take it to the next level & enter competitions with his board.
I suppose at least it keeps the requirement for safety equipment & giant concrete skateparks to a minimum :0)
Happy weekend everyone!!
