Stars with beams of visible light coming out of them and they all happen to be pointing out way. There was a undiscovered nebula passing by that scattered the light so we could see the beams. The rusty bin look is actually noise.

I'm thinking a old barn with a metal roof.

Rusty metal drum yes. Otherwise no. Any ideas about the context? What about the green?
A nearby copper rich nova is a thought but not really close.

Bjorn,
I have just started taking RAW pics on my D70S as I can manipulate them on my ACDSee software. I will be taking some big Tesla effects pics soon and will need to maximise the clarity and colour depth on my new wide angle lens.
(I know you told me to do this over a year ago..)
For the non-photographers, a RAW file compresses the original 48bit colour depth 6 Mega pixel file that is 50MB down to 5 MB. JPEG will bring it down to 300K in "fine" resolution. Or something like that.
This pic started life as a RAW file (Nikon NEF). Of course, no advantage here and mainly of use if going to be printed in magazines or books.

Looks to be a large drainage pipe that has a few leaks on a sunny day... Although the stuff at the end almost seems to green to plants...

The smoke was a give away since I only use this for lasers, and the Vortex generator. Ohh, and to simulate a burning car thief confused

The drum has been in our yard quietly rusting for years. As there is a 2 foot hole in the front, a few pin holes are of no consequence, but look interesting from the right angle in sunlight. The green is my new fibre backed green cloth of the diaphragm.

Err, you managed to summon Satan but he had gone up by 16.7% due to inflation?

Hmmm, perhaps the spinning electrode has a nonconductive section in the middle that arcs over?

Long exposure, spinning breakout point, pointy metal bits on the floor?

I see some corona in mid air, and a strange orange spark.

Long exposure? Yes - sort of. About 0.5 - 1 second. I will look it up when I get home.
Spinning breakout point? Yes
Floor is a stone composite tiled in a Penrose pattern but pointy bits? No
Corona in mid air? Yes - coming from other parts of the spinning breakout point.
Strange yellow spark? Easy enough if you have seen my other recent stuff.

Still no-one has the answer. I wouldn't have predicted it either but I think I understand it now.
