OMG. I hope the student that thought that up was given a very low grade. If it was a professional dresser-upper (as I call them), then they should be taken out and dressed in a handkerchief hat, string vest, pink Bermuda shorts and black wellies for a whole six months. They would never do that siht again.
My middle daughter is in advertising. I sent this to her. She said it reminded her of a job her company did a few years ago, a vinyl sign for a business on East Beaver Ave. in NYC. She said they had to keep sending replacements for the letter "s."
I saw a YouTube video some months back of a guy riding one of these and he was jamming on that thing! It was great fun to watch. I don't know how I'd find the video to share it here. @Fourbears, does this contraption go by a name??
