Antlers have been a recurring theme for me. It started out as a bit of a joke, but the joke's on me, as it is now a part of my work. I did a whole series like this two years ago (drum set, photocopier, boombox, gumball machine, all with antlers) - have a look. Antlers are a pretty awkward thing to add to any object. And awkwardness = amusing.
A note to bloggers and tumblrs: If you plan on posting these, please don't put up the whole series on your site. That's greedy! 3 or 4 or 5 is good, then put a link to this post. Thanks so much for spreading the word!
