http://www.neo-fukuoka.com/
also known as neo-fukuoka bike. Ok so other people have tried building this bike, but they are the only ones (that I know) that have a working bike that is as close to the original Manga design. Comes in 250cc or 400cc engine sizes (typicall japanese crap) and costs to order around $20K
