“These are the mind-blowing artworks of one professor who has dedicated his professional life to studying and generating a series of dizzying optical illusions. Professor Akiyoshi Kitaoka, from Ritsumseikan University, in Kyoto, Japan, has spent more than a decade creating his collecting of stomach-churning works. His designs have been used by the likes of Lady Gaga, who ran the Kitaokas work, entitled Gangaze, as the CD cover for her album Art Pop, in 2013”. – Caters News.

Cordwood construction is a method of natural building that originated roughly one thousand years ago in Greece and Siberia. This method involves using pieces of wood that slightly protrude from the mortar, giving the walls an attractive appearance. Usually, the walls are made 12 to 24 inches thick. However, in some parts of Canada, the walls can be as thick as 36 inches. This method appeals to many people due to its ease of construction economy of resources. Cordwood Construction can be separated into two main types: mortar-insulation-mortar (M-I-M) and Throughwall. M-I-M is a more preferable and widely used choice as it allows for better insulating properties.

In order to get a glimpse into the visual culture of drug trade in New York City, a British photographer Graham MacIndoe collected more than one hundred bags, which were used to sell heroin. These bags feature references to various movies, fast-food restaurants, and luxury brands. This could be a way to mark various purities of heroin, or maybe different drug dealers use different markers to distinguish between each other. We can only wonder where Graham has acquired all these heroin bags. Hopefully, he picked them up after their contents were emptied. (Photo by Graham MacIndoe)

We all have our own ways of passing time on our daily commutes. Some people read, others try to sleep, and many listen to music or play on their phones. But one creative commuter has a simple and highly entertaining way that hopefully more people will embrace.

In Jukkasjärvi, a village a few miles east of Kiruna, the proprietors of one hotel begin planning for a winter ice festival in March. That’s when they begin collecting some 5,000 tons of ice from the River Torne in order to prepare the Icehotel, the world’s coolest place to stay. Options for overnight stay include snow rooms, ice rooms, art suites, and the Northern Lights room, all of which range from about $300 to $900 per night. But the deluxe suite’s the only way to go. These rooms come with a critical amenity: heated ensuite bathrooms and saunas. Here: A man walks into a room in the Ice hotel in Jukkasjarvi, Sweden, December 16, 2015. (Photo by Ints Kalnins/Reuters)
