Abstract: A pen cap that has a propeller attached to the shirt clip found on many pens. The propeller is designed to rotate about a fixed shaft as an amusing diversion for small children or bored executives. An alternative design has a hinge mounted at the top of the clip that allows the clip and propeller to rotate 90 degrees. This increases the range of amusement for the device.
Abstract: A device for controlling the movement of an electrical cord which connects a computer mouse to a computer. The device is made of a shackle made of a partially cylindrical body having flared lips which extend along the shackle body and a mounting structure attached to the shackle. The device shackle attaches to a mouse cord and the device mounting structure is attachable to stationary objects such as mouse pads or desk tops. The device limits the movement of a computer mouse cord to a length necessary to operate a computer mouse while restraining the remaining mouse cord length by allowing the length of mouse cord between the mouse and the shackle to be moved while the length of cord between the shackle and the computer is held stationary by the device.
