During our recent trip home to visit family in Texas, we wandered around Sam Houston’s old home site in Huntsville. I was struck by the sheer genius of the joinery on his home - those logs, once in place, weren’t going ANYWHERE!
BOnus points to anyone who can figure out how to do this on a GlowForge. 
Dovetail joins. We’ve figured out how to do it, but it’s not very efficient.
Gradient engraving takes too long, and using a jig is very limited - size wise.
There is a wonderful half and half method though that I’ve been planning to incorporate - I’ll have to see if I can find the link.
It’s quite different than a dovetail joint. Sort of a hybrid joint. I bet some joint expert here has a name for it.
Ahhh! That’s it! Many thanks! 
To me, the genius of the joined is that the top sides of all the cuts shed water out of the joint. Houston isn’t Seattle, but I bet it will look the same in another 180 years.
Cool! I’d call that a compound dove tail.
