Is interpretative dancing to the Golden Ratio a good Geometry project idea?

Our group project is to report about the implications of the Golden Ratio in engineering and architecture.

I'm thinking of making an interpretative dance about the golden ratio. Bodies as buildings and music as math.

Do you think this is a good idea or should I stick to conventional wisdom?

I do want to D3fy the project (D3 is Definetly Defy Definition)

I don't know how to type equations out, like squared, etc. So bare with me. You should be able to see what i am getting at.

1) x - 2y = 11
x + 2y = -13 Answer x=-1, y=-6

2) x(squared) + 6 - 40 = 0
answer x=-10 and 4

I am just asking what they are called. Thanks.

in -2x = - 3.....should I put -2 under both so it would = -3/-2 which would make it 3/2 because of the two negatives or should I put a +2 under both which would = -3/2
thanks
