process of abstraction - 5 steps.
Since the OHP was the most complex object in sight in the Lecture theatre, jael and I decided to draw it. And it was actually rather problematic initially, trying to simplify it because it was full of angular shapes especially rectangles. We were just figuring out how to simplify them and someone said it was difficult to make this abstract because we do not have curves to straighten. Then the idea hit me - why can't I do it the other way round? So here it is, curving in the progress of the abstraction.
