methods and increased computer capabilities now allow direct
calculation of the decay of the kaon into two pions to be carried out
using lattice QCD. Recent results for the complex, I=2, K -> pipi
amplitude A_2 with physical kinematics will be presented. Initial
studies of the more difficult I=0 amplitude A_0 will also be described.
These studies give insight into the Delta I=1/2 rule and, when combined
with new methods that will also be discussed, lay the foundation for an
accurate calculation of the direct CP violating parameter epsilon'.
