It reportedly took the guy ten months to complete his giant Transformer. According to Gizmodo, “The superheroic machine took 400 drawings, 40,000 rivets and nearly $10,000 worth of stainless steel and iron.”

It’s unclear if the girlfriend accepted the marriage proposal. But this dude gets mega geek points for his efforts.
