Mellotronists

There have been great sightings in the Pacific Northwest--(green and 
red washes) and I have relatives between Rankin Inlet and Iqaluit 
stating the shows have been spectacular the past five days. It's just 
that when I was young I remember seeing the "curtain rippling" effect 
Northern Lights fast-forwarded on older educational films...and in 
real life all I've seen were the soft smudgy steady glows...
