I've tried doing some searches but I haven't found anything about this.
What about doing a 3D gallery of all the cabinets from the Arcade Controls members, with Sketchup? Not a huge file of all the cabinets, but a place where people can upload their Sketchup models?
And for members not willing to make the 3D themselves but wanting to have their cabinets listed, they could simply post artwork files and their plans and others could make them.
Basic categories would be needed: jukebox, full-size arcade, cocktail arcade, bartop arcade, miniature arcades - these four should fit 99% of the cabinets out there I guess.
So, what do you think?
P.S.: I guess simply adding the possiblity of a Sketchup file next to the cabinets in the Gallery of Projects of the wiki would be enough.
