I'm having trouble getting this webm video to work as an animated theme. Dragging the .zip to the themes page does nothing.
I encoded it myself trying to match the samples @ opera.dev. Could anyone give it a try?

It's an Earth 'timelapse' form the satellite Electro-L.
Btw, using the "themes > create your theme" feature can crash Opera.
