Abstract: A ring toss game such as played on a lawn or at the beach which can be easily moved or carried to a new location, is disclosed. The rings used in the ring game are made from recycled material, such as used tire sidewall segments produced through a removal and an inversion process to provide the needed physical characteristics, such as rigidity and aeronautic stability, whereby the tire ring segments can be adequately tossed across a playing field in attempts to score points by landing the inverted tire segments around a scoring post. The ring toss game also includes additional novel characteristics, such as game rules and scoring posts made from recycled material, and may additionally be provided in a carrying container which collectively move all the parts of the game in a packaged fashion to store or relocate the game.

Abstract: A kitchen ensemble includes one or more appliances and one or/more cabinets. Some or all of the appliances and cabinets have windows made of a material having a controllable opacity. The windows are opaque in the normal state, but can be made transparent by operation of a suitable control. Therefore, one can view the contents of the cabinets and/or appliances without opening any doors. The invention therefore enhances the convenience of using the kitchen, and saves energy by minimizing the number of times a refrigerator or range door is opened. It also enhances the aesthetic qualities of the kitchen.
