Depends on the kind of location you're decorating I guess
To me, this looks like something EE students might come up with to spiff up a "studying room" or something like that. Or maybe ( I know this happened somewhere near Vienna) an old power plant has been converted to a dance/concert hall and this was someone's creative idea of reusing parts of the old switchgear for what people who don't know anything about electricity might consider an "authentic look" but with a funny twist.
I read the comments on the power strip and now have four possible explanations: a) the strip is intact and has only been encapsulated for the fun of it.
b) the strip has been encapsulated for better mechanical protection (it's a household grade item and they usually don't stand being bashed around very well, but many construction guys still use them, even broken and "repaired" with paper masking tape)
c) the strip was broken and "repaired"
d) the strip was intact and encapsulated to float on water... the scariest possibility.
Both might just be jokes, remember the electric BBQ in the swimming pool with the power strip floating on a shoe! The pictures were actually staged in the aftermath of a LAN gaming party and the whole shebang wasn't connected to anything. Still, knowing some of the things people (especially first generation immigrants from some of our neighboring countries, but Germans and Austrians too) can do, the first one could be real.
