A friend in Houston just sent me a link to Oobject, a Website that compiles sets of pictures of all kinds of strange and funny things, such as the best cardboard Halloween costumes or the strangest floating buildings. One that caught my attention is 'terrifying mining gear' - chosen, it appears, based on the number and size of drilling bits on continuous miners and such. A few look like robotic dinosaurs with bits instead of teeth and claws.
I saw some of these or their cousins, at the MinExpo in Vegas not long ago. They all attracted crowds.
