My Rubbish Plotter
I had done the Hilbert Curve. This class is not very troublesome, but the other supported classes are... e.g. Dynamic resizable array. Well, anyway, the plotting was quite good. At least I could recognize them. And the iteration could go to at most 3. In the higher iterations, the plotter was not capable to plot so precisely.
I was also trying to design the new CS logo, but it did not look good... so... I'd rather not to show it... =P
