Our friend Masashi Togami, the founder of Team Back to the Future, has anew BTTF project on Lego Cuusoo: Doc Brown's Jules Verne Train. Like the soon-to-come-to-market Lego Back to the Future DeLorean, this model-created by Sakuretsu-is extremely well designed and fully functional.
Sure, the train doesn't actually fly, but it moves. It's fully powered by Lego's train engine.
