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. <br>

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.<br>
