With their hidden identities, which basically launched their world-wide success in the music business, many have attempted to re-create Thomas Bangalter's and Guy-Manuel's uber-sweet looking helmets.
Starting in early August 2008, I went out and searched teh_intarwebz far and wide for instructions on how to make one. No such luck. However I did find a Pepakura File of both Guy's and Thomas' helmets. Along with some fan-created helmets. I found it, I found my 'End-of-Summer-To-Late-Fall' project.
Step 1: Pepakura Viewer
I have made Thomas' helmet, but if you are looking for a challenge, use some of the tips from this instructable to make Thomas' helmet.
First, you will want to download Pepakura Viewer, which is a program that lets you view paper craft items that other users have made.
Once you have downloaded Pepakura Viewer, download Thomas' helmet, here. I didn't build the full helmet, as I knew ahead of time that my head was too big for the paper version. So I improvised, and used a hard-hat as my base, and attached the front of the paper helmet to it with masking tape. I'm sorry that I don't have any build pictures of the paper helmet face part. When cutting out the shapes, each edge has a number, which you tape/glue/attach to the corresponding number.
