A method of moving an object includes a step of fixing the object to an object-moving device, a step of moving the object to a prescribed position by the object-moving device, and a step of releasing the object from the object-moving device. In one embodiment, an attachment apparatus for a ladder includes a main support adapted to be coupled to the ladder approximately parallel to the rungs. The intrusion detection system also comprises a detection device configured to compare the first images with a background image of the monitored area. Additionally, the hand rest is lightweight and easy to install on either an easel or canvas, making it readily portable.
