there are many possiblitities for artwork on the three subjects:
1) we could use the golden ratio and create a spiral and with the spiral we can use the concept of symmetry or the things we learnt about fractals to generate either a symmetrical piece or a representation of a curved fractal.
2) we can use the pascals triangle and use it to draw the proof of the golden ratio (the squares) and have a patterned rectangle.
3) create a basic fractal and use symmetry to divide shape (trapeizium) into two and in each smaller shape we can draw the golden spiral in each divided segment which progressively gets smaller. (starting diagram is the sierpinski triangle using trapeziums)
