“Show us our butts! Mucawana tribe – Angola. In Soba village, the Muhacaona (Mucawana) tribe, perhaps the best place i have visited. They use cow dung and fat to make this so nice haircut, and love the beads. They asked me to make pictures of their backs... and butts to see on the camera screen if everything was perfect!”.

We already wrote about the Russian “Serebro” trio. Good trio, passionate. We recommend you their last music video. Very fierily (but don't show to children). Have a nice weekend! And... God bless Russia! %)

“Finger Icons” manipulation series by Ditology. Among the characters is a number of historical and contemporary personalities such as Dalai Lama and Jesus Christ. Very nice! Photo: “Dito Steve Jobs”.

The book “Elektroschutz in 132 Bildern” (Electrical Protection in 132 Pictures) was published in Vienna in the early 1900s by a Viennese physician named Stefan Jellinek (1878-1968, a founder of the Electro-Pathological Museum). The pictures are nice and direct and unambiguous; they teach, graphically, that the surest way to kill yourself with electricity is to form a complete path from source (usually the bright red arrow) to ground (the screened back, pink arrow). Arrowheads provide the path for current flow. (Photo by The Vienna Technical Museum)

Brian Anderson has been taking images of Glasgow for 20 years, spotlighting both the light and dark side of life. Brian, 40, said: “Glasgow is full of character. It’s a nice city, it’s a crazy city and I want to show all that”. Photo: Police look on as a man tries to break up brawling women in Queen Street. (Photo by Brian Anderson)

The Rogz Grinz Ball Dog Toy is a fun creation by South African Porky Hefer Design. The bounce and fetch toy will turn your dog´s mouth into an hilarious ear-to-ear grin, just like Milo dog from the movie “The Mask”. The toy can be stuffed with your dogs favorite treats and floats nicely on the water.
