A self-made billionaire came up with these wacky concept buildings - including a 'sexy' leg tower

Vasily Klyukin has been described as a "Russian-born Tony Stark." The self-made billionaire earned his riches in banking and real estate before dabbling in science fiction and architecture. In 2015, he purchased a ticket to become the first potential space tourist from Monaco, where he lives.

Now the modern-day renaissance man has published a collection of renderings of wacky skyscrapers around the world. They include a residential tower and hotels in the shape of a "sexy leg," a champagne bottle, and a cobra, which changes color much like a snake sheds its skin.

So far, none have been constructed or commissioned.

Tech Insider spoke with Klyukin on the inspiration behind his jaw-dropping buildings.
