Japanese company Real-F has your next halloween costume sorted with their 3D face replicas. Here's how it works: The company will shoot a picture of your face or head and then imprint the image on a vinyl resin chloride which can then be made into a mold. You can get either a mask-type replica or a model, which would be a mannequin-like model of your entire head. But make sure you're ready to cough up the cash: A mask replica costs upwards of $3,000 and a head replica more than $5,000. Check out more pictures on the company's Facebook page.
