Back in the day, like in the mid 90s, Beck, a really awesome musician, began performing shows with a horse head. He would wear the horses head and he would sing and dance and it was awesome. Even though Beck was a pretty influential artist, this was pre-blog or twitter or pretty much anything that makes things go viral, so only the few thousands of fans that saw him knew about the horses head. Fast forward to 2012 and it seems that the horse head is synonymous with being alive, or being a human or a dog. Basically you will see it everywhere.
