A Variety of Traps

[Polyedit2000]

Interesting that some of these designs are based on animals.  Let's see if I can rank them.

Antlion:
Camouflage- It's a big hole in the ground, so unless it gets covered, most people could simply walk around and avoid it.
Capture- It is surprisingly effective if someone falls in as the round shape forces fall-ins to the center and delay escape attempts, which gives the trap time to grab the victim.
Restraint- Not only is the trap difficult to remove once fully inserted, but it retreats underground to prevent others from discovering it.

Pool Table:
Camouflage- If the trigger is hidden by a rug, it could be possible that others can play the table as long as they don't step on it.
Capture- A person may be able to dodge the initial straps, and there may be a second escape attempt after the wrapping.
Restraint- It may be possible for the victim to slip out from the focal point strapping, but the wrappings would still prevent most movement.

Stingray:
Camouflage- It hides in the water, so while a person may not realize it could be a trap, it also limits where they could hide.
Capture- It jumps at the victim.  Assuming this is an aqua-jet propulsion, it might not be able to adjust if it misses.
Restraint-As a straitjacket, it still offers movement but at least prevents fighting back.

Honeybee:
Camouflage-There's not really much disguising it.
Capture- This assumes that the victim has a sense of smell (clogged nose may avoid this).  Otherwise, the trap seems to be unavoidable depending on the terrain.
Restraint- The sack design would make it difficult for a person to move.
