I'm going to say something your friends have been afraid to tell you: You could stand to lose a few polygons.
Here's a blank canvas for the new you. Or your Halloween costume. Or maybe your audition for store mannequin. Or your general purpose anonymity needs.
Sometime in the future I hope to make a full head version, but I wanted to post what I've gotten done so far in case someone could use it for Halloween 2012. The original idea was to make a papercraft alternative for artists who can't afford the "planes of the head" plaster model, so keep your eyes peeled for further developments.
I'm going to make a mask with dark paper, and use glow-in-the-dark tape to highlight the edges - I'll be Wireframe Man!
EDIT: Since originally posting this, I've seen comments by people stating they intend to make the make the mask using materials other than paper. Please note that many of the polygons aren't true flat planes, and there are a couple of twists that are challenging enough with thick paper. This mask, as designed, is impossible to build using rigid materials.
EDIT: 10/31/12 - Thanks for all the email messages, comments and photos I've been getting! I'm overwhelmed by the response. I had a family emergency these past few days, and the good vibes sent my way helped keep my spirits up.
The mask comes in two flavors: "black lines" and "faint lines", which has light blue lines, giving a cleaner look to the final product when used on white paper. There's a complete zip file for each version, or download the pages as separate pngs (be sure to download using the "original image" link when downloading the pages individually - otherwise your mask will be the wrong size).
(I've also included the blend file I used to make the mask, and the pdo file for those who use Pepakura).
Print the mask on stiff cardstock or bristol. IMPORTANT: Make sure "scale to fit" (or similar) is OFF when you print. The art will fit on US Letter and A4 (though page 1 is a tight squeeze on A4).
When choosing paper and glue, keep in mind what the humidity from your breath and sweat will do to your materials.
Before cutting out the pieces, score all the fold lines with a straight edge and scoring tool (I've been using a mechanical pencil with the lead retracted, but a paperclip is good too. I wish my real scoring tool would stop wandering off somewhere).
I didn't mark the glue tabs, they seemed self evident. Let me know if I was overly optimistic in that regard.
The mask fits my face fairly well, and the ear hooks work ok. You might need to cut them off and use the traditional elastic band instead.
Enjoy the new, chiseled you!
