+==IV: Butterflies==
+''Again in this sketch I benefited from unexpected "errors" while trying to get more into arrays and their use. Originally I just wanted to create different rectangular forms that are kept in the frame like fish in an aquarium and step back when they reach the boarder. But what i actually got was some pixelated flickering things, that, I guess could be seen in an abstract pixel art universe as butterflies. Obviously I still don't understand arrays and there consequences for following code lines fully, but I like the result and kept it.''
