Harrison Krix from Volpin Props was commissioned to create a replica from one of the members of the French techno group Daft Punk. This helmet was the fruit of 17 months of work. He chose Rebound 25 as the mold material to create a one piece glove mold and Plasti-Paste for his 3 part mother mold. To create the helmet itself, Smooth-Cast 300 was chosen to create a thin walled casting.
Additional information about the entire process can be viewed on his blog: Volpin Props Blog
Here is a YouTube video outlining the process:
