I found this and thought it was funny and interesting and at least somewhat tech related. I was always a Marvel comics fan, but you can’t deny that Batman is much cooler than he was when I was a kid. Back then all we really had other than the comics was the super campy BAM – KAPOW – ZAP Adam West 1960’s TV version.
I liked the late 1980’s early 1990’s Tim Burton versions, darker and more serious and realistic, but the Christopher Nolan Dark Knight trilogy got much further into the technology behind Batman. The first part of the trilogy not only showed how he got the training he needed to fight crime as the Caped Crusader, but also explained where he got all his gadgets, and how he developed it further as he needed more and more advanced technology.
This really cool infographic (created by moneysupermarket.com) shows just how much it would cost for Bruce Wayne to build and create all the equipment, vehicles, weapons, armor and even Wayne Manor and the Batcave.
