I do not know enough about SOPA or PIPA to support or oppose, but I note that everyone from Wikipedia to Google are flying blacked out sites or logos to protest the proposed laws.
Rather than jump on a bandwagon that I know nothing about, I am simply posting a nice black square.
This is what inside of a den looks like to a working terrier.
There is no light at all -- there is only pure darkness, and the beat of the dog's own heart, and the faint beat of another up the tube.
There is only the scent of fur and urine, water and mold.
There is only the sound of my shovel above, and perhaps the growls, clicking teeth, and rumble of rock and dirt ahead.
This is the world of the working terrier.
