This trivet sports the pattern of a leaf structure. The multiplex material shows it's strong grain in each detail.
My build was done on a desktop cnc-machine by Stepcraft from 6 mm birch plywood using a spiral-toothed 1.2 mm flute.
A laser cutter might be a good alternative tool to create one like this.

I took a random macro shot of a leaf. Then I did some photoshopping to tune the details. Then I used Illustrator to trace the pixel image.
