Object2dDisplay displays 2d arrays of objects..
Object2dDisplay helps display 2d arrays of objects. Create a Object2dDisplay, give it a Raster widget to draw on, a Discrete2d, a message to call on each object, and (optionally) a collection of objects and it will dispatch the message to all objects with the Raster widget as an argument. In addition, Object2dDisplay can help you make probees.
