Right now, I have a v2 prototype kicking around for testing with the parents-to-be.

The v2 version is the first to have a CNC milled enclosure, so I'll be revising the CNC designs in the next round. The software is more or less done, at least until I can hear some feedback from the actual users. If you look at the repo, you can see comments (and earlier commits) that show an idea about allowing the brightness of the light to be controlled - I tested that a bit in v1 but took it out for simplicity while I test it.

The v1 version was a gross affair molded out of shapelock. More like a Louise Bourgeois nub than a prototype. Its main purpose was to let me measure how much coaxial alignment the coils need (the answer: a lot).
