My process were fairly simple:
1) Draw a straight line that divides the paper into half. It can be vertical, horizontal or diagonal.
2) On both halves, draw a semicircle (bigger is better!). They don’t have to be the same size.
3) Divide the semicircles into halves.
4) Repeat step 2 and 3 until no more semicircles can be drawn.
I’m fairly satisfied with the results, although one wasn’t carried out as much as I would have liked. It’s pretty funny that they all decided to divide the paper diagonally in the first step, I think it might have been due to the way I worded the instructions. It would be an interesting psychological experiment to do the same exercise but worded slightly differently to see how results turn out.
