While not aesthetically my type of bike it does showcase their talent in engineering and craftsmanship. It sure will draw more attention at an event than a standard chopper and some business cards. 
No disrespect intended to the builder nor anyone else here. In fact it likely will only illustrate what I don't know. But I have no idea if that showcases any engineering mastery or extraordinary skill.
It's a lot easier to hang pieces together in a visually different or interesting way than it is do that same thing in a way that has any rationale to it from an engineering or practical perspective. That bike (thing?) is far enough afield from the norm I've got no idea if it'd be at all rideable. Seeing things like painted plumber's tape holding on rear lights and a few other equally cheesy (cheap) doo-dads I don't think it's a great exercise in craftsmanship. And as for a stellar engineering exercising; I honestly don't have a clue

.
It certainly looks interesting from 10 feet away. More than that, however, or zooming in on a lot of it's details; it's hard for me to give the beastie more credit than that.
