Cutting out shapes with a computer controlled router / cut-out tool.
Circles, ovals, squares, rectangles are drawing tools in the CNC software. They can not be angled - if you wanted the grain at an angle.
The plaques, duck, star, heart & unicorn are free carvings I download from the internet. There were 2000 all together.
The CNC software comes with a small set of fancy carvings also. Filagrees, rosettes, shells, Fleur de Lis, etc.
You'll notice the unicorn did not come out very well - it was reduced from 8" to 3" - it lost detail because the cutting bit is too large - 1/8" dia.
The Baltic birch plywood is approx. 12"x24"x1/8".
