Cool, from 1 to 7 third party modules in the space of 2 months. Great stuff.
I had a quick play with the patch that's included in the zip file, and I think that this is what's going on:
The module outputs an LFO like modulation signal, whose frequency (etc) are controlled by the positions of the other knobs, each of which can itself be modulated.
I'll post a bit more detail once I'm sure myself about what each knob does (I'm thinking Frequency, Offset, Amplitude, Shape?).
I don't expect a manual with free devices, but a few words of documentation might help get us going (especially with some of the other modules you've posted

But then, experimentation is all part of the fun isn't it!
