Clustering, Order, and Collapse in a Driven Granular Monolayer
Phys. Rev. Letters, 81, 4369 (1998).
An instantaneous picture of an inelastic collapse in our experiment.
The particles in the collapse are at rest with respect to each other.
The surrounding "gas-like" particles, however, remain in motion.
Scroll down to see a "time-averaged" image that demonstrates this two-phase behavior.

MOVIES!!!!!!!!
we suggest QuickTime Movie Player
The one to see if you only have time to see one:
Collapse Nucleation (23.2 Mb) (it's the REALLY cool one)
If you have the time, here are other movies
Gas phase Movie (5.2 Mb)
Zoomed Gas phase Movie (1.4Mb)
Zoomed Collapse Nucleation (4.4 Mb)
Ordered Phase (6.4 Mb)
Zoomed Ordered Phase (2.4 Mb)
Evaporating Collapse (35.9 Mb)
(The movies are a few Mb each)
A 30 frame, 1 second composite image of a collapse in the experiment.
The motionless condensate shows up as sharp peaks of high intensity.
The surrounding "gas-like" phase is the lower intensity background.
