Yeah I'd agree that the first symbol looks more like a personal icon. It might be of the person who drew it (so it might appear in about the
neighbourhood), or that of a specific target the second symbol was drawn for. It may have been auto-drawn as previously mentioned.
There are two possible scenarios I can think of, the first being the machine was playing up and someone was "exercising" the machine for you. Since
the machine is now broken, I would be inclined to believe the trap is empty, so you might as well clean it off.
Another possibility is that the trap was drawn to imprison an entity that was outside the machine, had nothing to do with the machine, and the machine
was simply a convenient surface. In this case, the trap might be full and rubbing the symbol off will release it.
I agree with the previous poster who suggested that it's important you try and locate whoever drew those symbols and find out what the intent was.
Have you drawn your own identifying symbol next to the others? The chances are whoever drew them visits that machine regularly and will notice your
note. Maybe they will contact you...
Machines are strange, especially electro-mechanical ones. Anyone who works with machines for any length of time develops "the touch". It's almost like
they have authority over the gremlins, and often a machine will simply start working again when the tech just touches it. I demonstrated this in
church once with the AV system that was not cooperating. A few people played around with it for about 20 mins and had no luck. So I said to them that
if they let me try, then I'd fix it just by touching it. They thought I was joking until I stepped in and touched it. Lo and behold it instantly
behaved itself and hasn't failed since.
When I worked on electronic devices as my job, I would fix maybe 10% of them in that way. Everyone did so it wasn't just me. It's an acquired skill
that is generally obtained near the end of an apprentices time.
Anyway, the reason why I'm sharing that is because I'm a firm believer in machines containing ghosties due to my years of experience. where they go
when someone with authority kicks them out is anyone's guess but once they go, it never happens again to the same device to my knowledge.
