The following clip shows Smartbird, a flight model that perfectly imitates the flight of birds, snip from Youtube:
SmartBird is an ultra-light but powerful flight model with excellent aerodynamics and maximum agility. With SmartBird, Festo has succeeded in deciphering one of the oldest dreams of mankind: the flight of birds.
The bionic technology carrier, inspired by the herring gull, can take off, fly and land by itself - without additional propulsion. Its wings not only flap up and down, but also twist deliberately. This is done by an active articulated torsion drive which, in conjunction with a complex control system, achieves previously unattainable levels of efficiency in flight operations. Festo has thus succeeded in making an energy-efficient, technical adaptation of the natural model for the first time.

More for you:
"Dravens Tales from the Crypt" has been enchanting for over 15 years with a tasteless mixture of humor, serious journalism - for current events and unbalanced reporting in the press politics - and zombies, garnished with lots of art, entertainment and punk rock. Draven has turned his hobby into a popular brand that cannot be classified.
My blog was never designed to spread news, let alone get political, but with current affairs I just can't help but capture information here that is otherwise censored on all other channels. I am aware that the design page may not seem "serious" to many in this regard, but I will not change this to please the "mainstream". Anyone who is open to non-state-compliant information sees the content and not the packaging. I've tried enough to provide people with information over the last 2 years, but quickly noticed that it never matters how it's "packaged", but what the other person's attitude towards it is. I don't want to put honey on anyone's mouth to meet expectations in any way, so I'll keep this design because hopefully at some point I'll be able to stop making these political statements, because it's not my goal to go on like this forever 
I leave it up to everyone how they deal with it. However, you are welcome to simply copy and distribute the content, my blog has always been under the WTFPL license.
It's hard for me to describe what I'm actually doing here, DravensTales has become a culture blog, music blog, shock blog, tech blog, horror blog, fun blog, a blog about found items on the internet, internet bizarre, trash blog, art blog, water heater, zeitgeist blog over the years , Scrap blog and grab bag blog called. Everything that is right ... - and yet not. The main focus of the blog is contemporary art, in the broadest sense of the word.
