Building off the Grid class built for Grid It! this is another command line game that was made as part of an assignment. Instead of posing a challenge though, this time all you have to do is supply a shape - this can be plotted by you using the on screen Grid (a painstaking exercise) or you can have the program read in the coordinates from a text file (recommended). Once you are done, just select an initial point on the Grid and watch as the program fills in the plotted shape - similar to the Bucket tool found in many graphics programs.
The assignment can be found here.
