So. I did some MORE research and found that there were tonnes of random item generators, so I scrapped that idea.
However, I thought of an SCP idea, that would be a random generator, but would only produce living organisms.
I've put a bit of thought into this, and the organism produced by the generator would depend on a couple of factors.
1: The concentration of particular gasses.
For instance, if the atmosphere surrounding the generator had a high concentration of carbon dioxide, it would produce plant-based organisms and if it was a high concentration of oxygen, it would produce a living organism (i know plants "live", but you know what I mean)
2: The temperature of the air surrounding the generator would determine what region the organism comes from. For example, if the temperature was very cold, I plant or life-form originating from cold regions such as penguins, polar bears, some species of seal, etc, etc, would form.
3: The humidity would determine if it was a sea/water-based organism or not.
Right now, I can't think of any more factors, but I don't think I'd want any more factors added to it, because it would ruin the "randomness".
Again, I feel like it would lay a pathway to some interesting logs, along with addendums, and special containment procedures (mostly who would have access to it).
Let me know what you think! If you think there are too many factors, ruining the randomness, let me know! But also if there arn't enough and you can think of more, also let me know!
