Ok that is a kewl collection of four puzzles.
There are a couple of threads about this book.
It looks really awesome. I backed it to get the plans only at this point.
I might be a little slow, but I did earn a badge for posting so I have that going for me
It’s all about getting badges! (and likes! )
I’ve double post a couple things in the past as well. It’s hard to keep up with all the threads and remember what was posted previously.
Keep posting interesting things when you find them!
We don’t need no stinking badges.
