  For a regular, compact, polynomially convex circled set K in C^2, we
construct a sequence of pairs {P_n,Q_n} of homogeneous polynomials in two
variables with deg P_n = deg Q_n = n such that the sets K_n: = {(z,w) \in C^2 :
|P_n(z,w)| \leq 1, |Q_n(z,w)| \leq 1} approximate K and the normalized counting
measures {\mu_n} associated to the finite set {P_n = Q_n = 1} converge to the
pluripotential-theoretic Monge-Ampere measure for K. The key ingredient is an
approximation theorem for subharmonic functions of logarithmic growth in one
complex variable.
