Still playing in the waves 
Six layers of 1/8" Baltic Birch, a lot of cutting for an 8" diameter and the burly runs great! 
~380mm X ~380mm work area, thinking of expanding for even bigger adventures!
EDIT: Changed pic to finished product, cut a ring of walnut to frame it.
Wow - very nice! That white foam layer must take a while to cut
Not too bad, it was a 1.5mm carbide bit and I didn’t want to push it, only took 23 minutes to cut, probably be measured in multiple hours if I had to do it with a coping saw and refreshments would be needed. 
Absolutely gorgeous!
Thank you! I probably became aware of the original print ‘The Great Wave’ more than 40 years ago and have loved it ever since.
One of my all time heroes, Jacques Yves Cousteau, said it far better than I likely ever will:
The sea, once it casts its spell, holds one in its net of wonder forever.
That is a long way from the start and a wonderful piece
