SuperRabbit-
Would I be willing to work on something so cartoony and kiddie? Are you kidding?? We're a bunch of adults building arcade games for crying out loud! Let's put it this way...I get jealous when my wife takes our daughter to Toys R Us without me....
I can hardly wait to get going on it. Like I said I do have to finish (or at least get close to finishing) the other projects I'm doing for people. In the mean time, if you could confirm the actual marquee dimensions (and note the area covered by the marquee retainers or trim-probably 1/2"-3/4" top and bottom) I can get a template started. If you could point me to the site where you found the Scooby vector art, that would save me huge amounts of time redrawing things.
If you're open to it I'd like to recreate the original Scooby logo, with the curvy ghouly type. If you'd prefer to use the movie logotype I understand.

When you lay out the control panel if you could do so in a way that would allow me to use your template to design CP art (around joysticks and buttons) that would be a tremendous help as well. (Assuming you want me to do a CP overlay). Laying it out in Illustrator (preferred) or even MS Word in scale would give me exact locations for buttons etc. I imagine labeling the buttons would be good for a kids cab.
So are you going to paint the sides green or use green laminate??? Will you use green/orange/violet pushbuttons? Oh, man...there's so many great possibilities with your theme.
A Scooby skinned front end (like Emulaxian) would be fantastic, especially for kids. Come to think of it, with Emulaxian's 3D arcade model support, your kids could actually walk through a Scooby themed haunted castle to find the games they want to play.

Just a question of texturing the walls will some Scooby stills. OK I'm sold....I've gotta do that too. What's another weekend anyhow.... Hmmmmm.... how fast is the laptop you'll be using?
But I digress...........
