Triple Sloths is from the Nonlinear Circuits lineup. IMO everything in their Chaos lineup of modules is very interesting and I intend to add more than one of those to my system in the next 6 months.
To my understanding, the Chaos type modules are basically an alternative to random modules. Some would say (and I would agree) that in general random is not very musical; the main use case I have for random is adding a small amount of it to various parameters. Chaos, on the other hand, is loosely patterned -- imagine for example a drunk person riding on a bike going around a figure 8 track; they follow the track, but not exactly. This type of loosely patterned behavior, many people including myself would consider musically useful: it is repetitive enough to indicate some type of cycle, but loose enough to never repeat strictly, and hence keep generating interest. My intended use cases for the Chaos oscillators is to add some "slop" to my other parameters, and combine it with other tighter LFOs to get a looser complex mod signal. Not so different from how one might use random, but IMO a bit more useful due to its semi-patterned behavior. There are surely many other uses for these types of chaos modules. To my knowledge, Triple Sloths gives 3 "chaos" signals ranging from slow, slower, to very slow.
BTW many other modules from that manufacturer look interesting (if somewhat baffling) to me.
Good luck, enjoy!
