Found this bunch of interesting warning signs. Kinda 90s style futurism but I dig it. Looking at them makes me feel like Johnny Depp in Fear and Loathing.

Chaos control is likely to be very useful in many future applications. But chaos is sensitive, so interfering with such a system might be unadvisable.

Exactly what kinds of hazards could occur with mature cognotechnologies is hard to imagine. This sign represents a general hazard, perhaps the induction of inconsistent beliefs, infinite loops or mistaken perception.

A warning sign for black holes, event horizons, naked singularities and other spacetime engineering hazards. Of course, purists will point out that orbits around black holes are just as stable as around any other mass – they don’t suck things in without some friction mechanism – and that many other nasty metrics are not even symmetric. But some physical realism ought to be sacrificed for visual saliency. A black spiral signals an obvious, dynamical danger.

My symbol is intended to both remind of a Penning trap (for early applications where we just have a few antiprotons) and a starlike explosion (for bigger amounts). It is also in reverse, to hint at the anti-aspect of antimatter.

A system that evolves freely is potentially very adaptable and creative. It could also become nearly anything, with consequences ranging from the annoying to the disastrous. It is likely unlimited self-evolution will need to be contained carefully even as we mine it for truly new inventions. The arrows nicely hint at a chaos-star as well as replication.

As we learn to affect our brains better there is an increased risk for addictions, to gain pleasure from something harmful or that we edit ourselves to like our current state no matter what. The poppy represents such motivation traps.
