I haven't seen anything that is a "plug and play" off the shelf integration yet, and to be frank there doesn't seem to be much demand for a generic integration of Fancy Product Designer straight out of the box, as-is. All of our clients have wanted something very tailored to their own business.
We've integrated the Fancy Product Designer a few times, almost always with the API version. Using their API allows us to do a completely custom integration to meet any requirements for configurable products, custom user interface, mobile navigation, etc. However, having someone build a custom integration does require a significantly larger investment of time and money than buying an off-the-shelf extension.
I'm not aware of any really awesome addon product configurator extensions for HikaShop. That's because the majority of store owners' needs are already nicely met with the use of HikaShop options, variants and characteristics. There isn't enough market demand to make a generic product configurator extension financially viable.
