Time series persistence

[Marcos Sánchez Provencio]

It is all in one slice, with a time dimension. I could replicate the
layer with a shifted view. Maybe it is too much work for the db server
just to get a pretty effect (but I'll try it anyway :-)

Thank you for the idea

PS Is it possible to have an animated gif as a marker?
