I followed Plowboy's link:

Wow.
I didn't see anything there that would work for me, right now.
But I wonder, if enough of us contacted Brett Brown, would he consider making fixed gear chain rings?
Yes, I know his geared chain rings will work on a fixie, but it doesn't seem right.
Anyway, visit the site and look at the workmanship.
The price seems very fair for what one gets.
