Each challenge has a very comprenhensive PDF explaining the algorithms used and screenshots of the application (click on each image to open it). The first two challenges were done using Java's AWT and Swing, whereas from the third challenge on, these were made with AWT/Swing and Processing (for the course purposes, no pre-made transformations where used, all were hand coded!).
Adding Processing into the mix was nice because of its simplified application for interactive sketches and the use of a main non-blocking event-handling loop.

To further show that the lines and circles are being drawn pixel by pixel, each pixel has been assigned continuous colors to show the iterative drawing, not all in a single stroke.
The lines turn green if they are inside the clipping area. Also the area can be dragged manually!
