Linux and BSD Funding VISA cards

I have just discovered that if you reside in the US, you can get a BSD or a Linux VISA card, so that every time you buy something BSDFund and LinuxFund organizations will get some money (I guess some cents) that then they will spend on funding some Linux/BSD free software projects.

This Linux Fund webpage, says that they are preparing to revitalize their other cards in North America and launch a card in Europe. Without any doubt, I would get one. Nice idea!

Here are the images:

Cute, aren't they? ;)
