He is currently working on v3 of it. v2 was more of what he did with v1 which was hack it together and try to get it right. He learned about half way thru v2 that method was good for prototyping and looking cool and was good for 'close enough' but was failing to get the control and precision he wanted. He ended up adding way more complexity than he liked. v3 he is starting with reduce part counts and 'how do I actually build this thing' and decent testing of each part iteration to find ones he likes.
