I have a friend who is having twins. I'm using some new woodworking techniques to make a pair of baby rattles for her. The real challenge is trying to make two shapes with organic curves and precise cuts that are as close to identical or mirror-image as possible, while also hiding the joints.

It's very low-tech. No screens, no CNC, the most technically advanced tool is the digital RPM readout on the lathe. It's nice to disconnect from my screens once in a while.
