Personally, I like conversions and renovations. It's like, I feel that I'm retaining the history of the cabinet, but breathing life back into it. Retaining the glory of the usage that was put into it way back when, and holding it's heritage of it's youth for the future. A make-over. It really depends on the cabinet of course...I wouldn't renovate a classic Pacman cabinet per say, but a standard dynamo cabinet, for sure. Perhaps I'm being too sentimental... or just too lazy to figure out dimensions and such.
Anyways, love the concepts for the side colouring and artwork!
