circular sock machines

I have found the coolest thing ever. I read about them briefly in grad school but they passed right over me like so much did in that era. Anyhow... they knit a tube while one turns the handle.. it's more complicated than that..but they allow the knitting of socks with a lot less time once you get the hang of it apparently. And I get to try one this weekend! this is a bad thing in some ways because frequently if I ingore new things long enough I lose interest... but tax return season is coming soon so maybe I can get one then.
