An image is essentially the Fourier transform of a wavefront, and the challenge of producing sharp images is one of keeping coherence across a wide wavefront.  The Hanbury Brown & Twiss effect is a surprising optical phenomenon that allows imaging without classical coherence. Though known for half a century, its application to astronomical imaging has been limited by technical hurdles.  But since about 2020, those hurdles are getting overcome.

This talk will explain the HBT effect and discuss the current landscape of technologies (from proven to challenging, futuristic, and crazy) and astrophysical applications (from interesting to exciting, awesome, and maybe even mind-blowing).
