Festival-goers enjoy a fairground ride at Reading Festival in Reading, west of London, on August 27, 2021. As coronavirus covid-19 infection levels rise across the country, vaccines will be offered to revellers throughout the weekend. The organiser of Reading and Leeds Festivals has said such events are arguably “safer places to be” because attendees have been tested for covid-19. The festivals are returning this year with headliners including Stormzy, after being cancelled last year due to the pandemic. (Photo by Daniel Leal-Olivas/AFP Photo)

Bryan Berg was introduced to card-stacking by his grandfather at the age of 8. He is a self-taught artist in all of the techniques he uses today. Berg's freestanding card structures are based on a grid-like arrangement, which Berg tested in a structural engineering lab to support 660 lbs per square foot―using no tape, no glue, no folding, and no tricks.

A photographer tested the concentration of several pairs of dogs as he captured their reactions to treat time in a series of shots.

Photographer Wes Naman has created portraits of his friends using Scotch Tape to distort their features. The results are similar to Scottish artist Douglas Gordon's 1997 work, Monster, but Wes says he originally got the idea after applying tape to himself to test a lighting rig set-up. Wes Naman has been a self taught photographer of ten years before graduating from commercial photography in his home in North Carolina. (Photo by Wes Naman/Rex Features)
