What is it?
like what material? It’s 1/8th inch birch plywood

These are amazing and super inspiring! Great work!! I’d love to try something similar. How do you generate the original artwork plan so precisely? Illustrator Fu?

thanks, was just gonna link that post. Surprisingly easy to do in Illustrator if you have a vision and a rudimentary handle on how to use the program! 
Oh my gosh, @Tony has been holding out on me! D: This seems super easy. I’ve already passed this on to my woodworking friend to see how we can make it into a coffee table.
The only problem with these is the massive amounts of material. That being said, if you could design it so your cut out piece from say the top was used two rows further down , then maybe you could save some. Thought I could also see some matched veneers doing this well.
Been looking at some wood turner forums and thinking about what it takes to make stacked ringed bowls from a board with minimal work. Turners cut the rings at an angle so that it can be put together using mimimal waste of wood and needing minimal material removal. Putting all these ideas together, given that the Glowforge can’t do the angle cuts needed, it seems that with three sheets of material, you could cut concentric rings with each successive sheet starting the ring offset by the amount you want the slope of the bowl. Do a glue up. Using a bowl sander tool smooth the inside of the bowl. Dusty, but no lathe needed.

Segment cutting has to do with a few things.
Less material and stability.
The main thing being stability, as the grain runs parallel to the circumference, so there is no expansion. (very stable).
I can see the GF being used to make segments.

Wow! Has almost an optical illusion effect. Thanks for posting.

Cool! Really interesting effect! I’m definitely tagging this for later inspiration.
Wild, I’m still trying to wrap my head around how to start designing one of these.
Do you start with the top layer and then just expand the strokes for each layer as you go back?
I suppose you could start with that strategy, but then you’d need some rules for what to do when the expanded strokes start to overlap themselves and other strokes. It’s not obvious to me how to do that in this example.
Maybe just a tile pattern done in 3d? You could have a separate tile for each layer then just rotate the tile for whatever size you want.

Can you link to the FB group? I’ve never thought to look for one. (It’s a decent community?)
Sorry can’t seem to link but search in facebook for two groups.
“Laser engraving and cutting” - really good group
"Laser & cnc cut patterns" - don’t overly recommend , not bad, a Russian post patterns for sale.
That is super inspiring!
