New lasercut spiral designs

I finished three new laser-cut spiral designs in the two days prior to Maker Faire.  I pushed on several new things -- intricate boundaries, using multiple types of wood in the same design, handling large numbers of pieces, and working with a new, bigger type of veneer.  All in all, it's really impressive that all three designs worked out more or less flawlessly.

Maker Faire

I spent almost all of Maker Faire behind a booth this year, but it was fun to interact with the various attendees.

 

In addition to the lasercut wood spirals, I brought a few laser-cut paper Hilbert curves for people to play with. 



Every now and then I would invite people to pull one of the Hilbert curves apart.  Because the Hilbert curve is an intricate, long, space-filling curve, a small Hilbert curve can be stretched to quite a length. 

This ~9 year old kid gave a savant-style mathematical definition of a Hilbert curve, so I let him pull the first one apart:



At the end of the day, we pulled apart the remaining ones, including the two big ones:

 


This is unrelated, but was also from maker faire -- a veritable ocean of paella:

Today's double entendre

According to the woman to whom the jacket full of patches belonged, this patch is a real sign from the Australian outback.
