Hey all, my first post to this forum and I'm already asking for things. Well, I have an advertising business I'm trying to start that invovles my car as a giant billboard for a company, mostly independent shop owners, on the side of my car. It is at it's very early stages in development, so far I have a 150 watt mixer powering two 60 watt megaphones on top of the car, a 16 inch LED scroll light in the back window, and a string of blue led light surrounding the roof, hood, and the trunk. But, I'm stumped on anymore ideas besides a weatherproof-led scroll light to put on the top of the car behind the speakers. Granted, this is some really low-tech stuff, but I'd be willing to invest time and money into something really cool for the car. I really don't even know why I'm posting this in a engineering forum, but I've met a lot of very creative and inventive engineers and hoping the trend was the same here. If I am in the wrong forum, please redirect me.
