Mystery solved
At least I hope it is. Thought I'd post the more explicit shot of the metal frame which none of us know what it is for.
There were at least 2 or 3 frames and I think I took pictures of 2 of them. Some kind of liquid metal goes through this frame like a sieve I think and eventually the frame has too much stuff on it and is not useable anymore. That's when it gets really good looking. This is all I know :)
