Some time ago I saw this yellow card magnet from Aerostich and I thought about making something for bicycling. I tried to contact some seattle bicycle advocacy people about the idea on myspace, but never heard back, so eventually I did it.

The other day I was reading some bicycling related articles on the Internet and found this one at crosscut about Peter Miller’s Yellow Cards. Peter writes about the origins of the idea,

… Aerostich copied them from my site after seeing them in the news, probably from the crosscut article. So the same steps happened, but in a different order. I think what you’re doing looks really really great. As you can see in my site, I originally posted the idea as an open-source contribution to the cycling community, so I am glad to see it expanding outwards.

I used to ride with Boston Critical Mass and came up with the Yellow Card in Chicago after a fatal accident occurred in front of my house (a bus killed a father of three). I really don’t like that Aerostich is charging a buck a piece for them (breaking creative commons liscence), but my desire to make it open source is a desire to encourage growth. It’s how market’s operate. Even after posting instructions on how to make them, I’ve gotten frequent requests to sell them. So I am really amped that you are choosing to give them out. That’s what I’ve been doing the whole time.

Lastly, you may find this totally pictographic iteration funny:

It’s really exciting to know this started with bicycling, and that there’s momentum behind it.
