found this and thought it was cool. raw equation: (3 * sqrt(4 - (abs(x) - 2)^2 ) + abs(x) - 20 - 4*y) * (3 * sqrt(4 - (abs(x) - 6)^2 ) + abs(x) - 20 - 4*y) * (x^2 + 4*y^2 - 100 * sqrt(abs((7 - abs(2*y - 1))) / (7 - abs(2*y - 1) ))) * (2 * (abs(x) - 3)^2 - 9 * y + 18 * sqrt(abs((2 - abs((abs(x) - 4)))) / (2 - abs((abs(x) - 4)) ))) * (-68 * abs((abs(x) - 3/2)) - 9*y + 54 * sqrt(abs((43 - abs((136 * abs(x) - 229)))) / (43 - abs((136 * abs(x) - 229)) ))) * (y - 5 * sqrt(abs((1 - abs(x))) / (1 - abs(x) )))=0
