In the first part of the 20th century, optical interferometers produced diameter measurements for a few bright stars and orbits for a few binaries. The last decade has brought new arrays and improved techniques. With these improvements has come a wider range of results, including limb darkening, orbits of triple systems, Cepheid pulsations, shapes of rapid rotators, images of circumstellar material, high-precision astrometry, and even detection of AGNs. I will introduce some of the current directions in optical interferometry and how the increased capabilities of current instruments have made them possible.
