Talks: Newton Institute (video, Cambridge 2010, go one level up for more talks), ICIAM (slides only, Vancouver 2011),

Introductory Physical Review Focus article by Mike Wofsey covering the first test on real pendulum experiment (also featuring small videos).
The basic mathematics behind it explained for a simple mechanical experiment (with animation but only based on numerical simulations).
The method has been used in a more advanced experiment with an energy harvesting mechanical oscillator recently by David Barton.
