Doesn't seem to be that weird to me. Since time and space can be rotated 
into each other there should be temporal counterparts to spatial 
crystals. Of course, loads of people will say stupid things about 
perpetual motion in regards to the crystals, but these crystals can't do 
any work.

It is a bit like how helium can be fluid at absolute zero: just because 
the temperature is zero doesn't mean there is no motion.
