    Abstract: The present invention' relates to a metal-sheet board or blackboard with magnetic features having two or three movements, which plots and represents reality in four dimensions (horizontal, vertical, depth and time) and which describes reality objectively, in which a T-shaped ruler is moved on a rail along the horizontal or X axis by a digital stepper motor controlled by a driver and software on the computer (horizontal movement). Furthermore, a tool truck surrounding the T-shaped ruler moves along the entire length (vertical movement) or Y axis thereof, actuated by a digital stepper motor controlled by a driver, which is in turn controlled by software on the computer, with these two movements controlled by mathematical speed and acceleration functions. A felt-tip pen or marker is placed in the tool truck against the surface of the blackboard in order to plot all manner of figures. Furthermore the tool truck includes a third motor providing movement perpendicular to the blackboard (depthways), together with the respective motor and driver thereof. Different scientific measurement tools and structures are mounted on the board or the tool truck and connected electronically to the different data input or output pins available on the blackboard by means of the driver and the related software on the computer, providing a real scientific measurement and laboratory instrument that interacts with the computer.

    Abstract: A creativity center (1) includes a base (100) portion that is connected by a hinge (200) to a board (300) that has opposed drawing/design surfaces on which artistic designs and markings can be made. The board (300) can rotate with respect to the base (100) via the hinge (200) and can be slid with respect to the hinge (200) such that the board (300) can be repeatedly flipped over and slid between two opposed 'use' positions with respect to the base. Thus, an opposed drawing/design surface (311, 321) configured in a 'use' position is presented to a user each time the board is flipped over. An eraser (400) can be located on either the base or on the hinge to automatically remove designs or markings located on the board (300) when the board is slid through the hinge. In addition, the base can include a storage compartment for storing art supplies.
