Abstract
Abstract A writing device including a barrel containing a battery powered motor having a shaft extending through one end of the barrel, preferably interchangeable writing tips and a connection to the shaft by a very flexible connector. The device enables production of impressions and designs on a writing surface whose character is dependent upon the flexible connection, the tip and the writing surface, and whose variety is limited only by the will of the operator. The device is useful for example as a toy or an artist's tool.
