There is GREAT interview with Cat Mazza of microRevolt up on We Make Money Not Art. Go read it and catch up on sweat shops, micro revolt, and her various projects: the Nike Blanket Petition, Stitch for Senate, Hackers and Haute Couture Heretics, and general crafty activism.
Cat is big craftivism hero of mine mainly because she's better at keeping up with the things I wish I was better at keeping up with, ahem, politics. But projects like the Knitoscope Testimonies, are more within my realm of knowledge and completely floor me with neato-ness. Knitoscope make video look like sweaters by lowering the resolution, pixelating, and translating the pixels into stitches that look like knitting. It's kind of like microRevolt's knitPro, but cooler and all the testimonials up on the site right now are from activists against sweatshop labor.
