The making of engine 428

Google+ seemed to like engine 428 so much that I even got a request to write a 'how-to' explaining how the picture was produced. The 'how-to' (actually a 'what-to-do'!) can be found here: http://www.fords.co.nz/downloads/428HowTo.pdf in PDF format.

Thank you to those who +1'd the original picture and I hope that you find the 'what-to-do' useful.
