beautiful math model made from math

this speaker cover is actually a mathematical rose. the floral pattern is actually a graphical representation of the equations r=4cos(2.5theta) and to r=3.4cos(2.5theta) they are overplayed to give the design some thickness. this rose could also be represented by r=tcos(2.5Theta) where 3.4=<t=<4.all those years of math pay off in their own way
