22 years ago my mom was -literally- having a labor day.
Yay me.

I have a Linux Fund mbna credit card that I got at LWE 3 years ago. It has a picture of tux on it. I'm not much of a linux advocate, and I have no idea if the fund is doing any well, but I like the credit card because about 20% of the time I make a face-to-face purchase I get this reaction:

"Oh, isn't that cute!"

So that doesn't necessarily make the logo cool, but it does make it somewhat attractive.

Only once have I gotten this reaction:

"Oh, cool, linux!"
