It looks really good, it would make a great design for any  pre assembled picture frame requirements.
I see a brief mention of a table saw, but nothing else , ... for instance a HCM and the likes.
I would be curious as to the construction method you used  to go about making it
Oh BTW it must have been a big splash as I see the bowl is fractured!

I think you have inspired me enough to do a replication ! ...standby!
