Publicly communicable interests contain the studies of gravitational waves in General Relativity. Although they produce deformations of objects (as shown on the video sequence for a ring of noninteracting particles with gravitational waves traveling perpendicularly to the screen), so far, no direct detection was reported. However, the strength is unbelievably small with the biggest expected relative deformations being ~10-22.
Another field of research that I work in are black holes and their horizons. The video sequence shows the transition of initially nonspherical past horizon in Robinson-Trautman spacetime into a final spherical one as time goes by (the time scale is in fact logarithmic).
The above animations are in open Ogg Theora or WebM video formats inside HTML 5 video tag. For the serious reasons why everyone should be afraid of the H.264 format read this.
