I know we don't do much here on Crop circles, or designs, as is now politically correct, but lately there have been two very intricate patterns that have gained a fair amount of coverage around the Internet, and on news sites.

The first one appeared in Oxfordshire, in Great Britain, and looks very much like a giant jellyfish. Its proponents are calling it a "one of a kind." It is a massive 600 feet in length. You can check it out at Oxfordshire Jellyfish.

A second interesting design was discovered in Wiltshire, UK, and shows what is being called a "dragon fly." This one measures 150 feet long.

Check it out at Wiltshire Dragon Fly Design. This brings us to our question of the day.

Are all of these crop designs man made, or do you think they could be an extraterrestrial hand in them?
