List of Gadget and Smart caches, or a cache where you need to "do something with an non-standard TOTT" to find or open the container.  Some are more intricate than others, from a simple trick lock or maze cache to caches that require batteries or special tools to open.
This list mostly contains caches in the North East and Mid-Atlantic States, but I'd be glad to add any gadget style caches you find to the list.
