Abstract: A musical keyboard that is collapsible between a deployed configuration and a deployed configuration. The musical keyboard including two or more modules, each module containing a different subset of a set of musical keys; and means for collapsing the modules from the deployed configuration in which the modules are arranged in a row to form the musical keyboard, the keyboard being substantially planar, to the collapsed configuration in which the modules are substantially positioned on top of each other.

Abstract: A prayer clock and a method for organizing the offering of prayers. The prayer clock has a face region bounded by an edge. The face region may include hour numbers and at least one hand. The prayer clock includes a plurality of slots adapted to receive a note or other reminder evocative of a prayer to be offered. In one embodiment of the invention the prayer clock may be provided with words or phrases referring to prayer, or with pictures, images, or artistic representations suggestive of prayer. In another embodiment, the prayer clock may include an outer border in which the slots may be located. The slots may be associated with the hour numbers on the face of the prayer clock, thus tying a particular time to the particular prayer noted on the reminder inserted in the slot, or otherwise assisting in the organization of prayers to be offered.
