The New Year brings in good things!
When I was learning how to knit, I spent a long time trying to cajole a friend of mine into making me the world's geekiest present: an emission spectrum scarf. It didn't pan out, but over New Years (and over drinks) we were circulating the idea around again and now it looks like Stern Lab is on assignment!
Becky over at Stern Lab is making emission spectrum scarves! Once she starts selling them at her Etsy store, you should go pick one up! Best. Present. Ever.
