In a new study, Suchow & Alvarez (2011) demonstrates a novel visual illusion whereby motion induces failure to detect change - or what they call 'silencing'. Look at the video embedded below. Initially, the dots are visibly changing in colour but once the rotation begins, the dots appear to stop changing or at least appear to change at a slower rate. Additional video demonstrations looking at brightness, size and shape can be found here.

They found that the faster the rotation, the slower the dots appear to change (i.e. stronger silencing).

In an additional set of experiments, they further determined that motion on the retina and not motion in space is responsible for silencing. Pretty nifty visual illusion huh.
