A reptile from Escher's artwork

A very interesting object was found at Google Maps near Ciudad Juárez in Mexico. It represents a single reptile from Escher's artwork "Smaller and smaller" (1956). Below you can see the original Escher's artwork and part of it with reptile in similar position.

This artwork is an artistic illustration of hyperbolic space. Due to properties of such kind of hyperbolic space you can infinitely go towards the center of the square but never reach it. Also Escher illustrated hyperbolic space in his artworks "Snakes", "Circle limit IV" etc.

Crop circles

Many people think that crop circles are result of UFO landing. They appears in darkest nights and we see their traces on grass fields. I will not dispute this opinion, because nobody contact UFO and wind of helicopter propeller looks more realistic reason of natural simple crop circles formation.

Inspired by natural crop circles enthusiasts croppers create own artificial crop circles. Often the more exact name for artificial crop circles is crop figures because they don't have rounded shape but more complicated. Croppers depict various types of figures such as polygons, fractals, artistic images. Every year contest of circle croppers is being taken at http://www.cropcircleconnector.com/

Below there are some examples of crop circles.
