Nice one, Hellfire! See, it's do-able, given a bit of time ...

The Copy Internet Image / Paste thing works well if you want to do, say, a quick tigerskin patterned ship with no logos (as our producer Paul demonstrated).

Copying the layout into Photoshop, editing it, pasting & testing it, back and forth into Photoshop etc - I'd suggest that's a good way, if you want to add details in 2D. Remember too, you only have 16 colours to play with.
