I hate rotating my vinyl board around on my desk. Usually, I've got the board setup ready to play through some game from a book. I go to rotate the board, because I'd like to be looking at it from black's perspective instead of white's, and off drops the rooks onto the floor (often joined by a pawn or two). The other scenario is playing chess with a friend and realizing, after the board is setup, that he's supposed to be black this time.
Anyway, my wife created this 'Lazy-Larry' (she suggested the name). Basically, its a chess board mounted on bearings so that I can easily rotate it.
It works great. I never have to worry about dropping pieces on the floor again.
What do you think?
