Now here's something interesting. Indigo Studios are a design studio in Atlanta Georgia (My favourite town!) who appear to be responsible for designing the current packaging for Nerf. They've got a case study on the process on how they design the images for the boxes on their site.
It's an interesting read, but what I'm really liking in the case study is they actually make reference to 1)The Whiteout series, and 2) have a look at the last two images of their CAD designs.. one's a Vortex Proton.. the other.. yup big ballz Stampede 50 round drum.. :P
Please don't hound them for more product information; they're designers, not manufacturers.
