Been working on a little something over the past week, I have to admit that excitement's got the better of me so I'm posting some poorly lit photos.
Anyhow, they get the idea across until I can take better ones (i.e. during the day and not at 3am

).
UPDATE: I decided to release the model layout, you can get it here: REMOVED
It's in PDF format and has no instructions, if you view the CG model for reference you shouldn't have too much trouble. Print pages 1 to 5 on stiff paper and 6 on lighter stuff. This will give you the Orion model without turrets and radar dishes.
EDIT: 03-03-08 - I uploaded the .pdo (pepakura), textures and the .PDF that I built. Feel free to use/modify/experiment, the only thing I ask is that if you make your own Orion please send me a photo or post one here.
