1. A compass configured to allow a party with reduced manual dexterity to draw circles and elliptical figures of a desired shape and configuration, said compass comprising:
a base plate having a generally flat wide body, said generally flat wide body configured to allow a person with limited manual dexterity to grasp and move said body, said body defining a first pointer and an arm connecting portion;
a selectively adjustable connection device, said selectively adjustable connection device configured to connect the base plate of the device to an upwardly extending arcuately-shaped arm in any one of a variety of preselected positions;
said arcuately-shaped arm having a first end desired for placement against said base plate through said selectively adjustable connection device and extending along an uprising arc shaped length to a second end, said second end configured to receive and hold a portion of a scribing device therein;
whereby a party places a scribing device within said second end of said arcuately-shaped arm, and adjusts said scribing device so that said a portion of said scribing device is in contact with a portion of a surface, said first pointer is placed in a desired center location and said arcuately-shaped arm is moved into one of said selectively desired positions, said base plate and said arcuately-shaped arm are thereafter rotated about said first pointer so as to cause said scribing device to scribe an arc of a desired size and shape about said center location.
