An arm holding a giant gun appears to explode through a wall, while elsewhere a man walks a tiger on a leash. These breathtaking pencil drawings are the work of 31-year-old artist Ben Heine, who lives and works in Rochefort, Belgium. The “anamorphic illusions”, part of the artist's “Pencil Vs Camera” series, appear slightly distorted unless viewed from the exact same perspective in which they were created.

Darth Mykolaiovych Vader, who is dressed as the “Star Wars” character Darth Vader, poses for a picture as he dries his mask and helmet with a hairdryer in the bathroom of his apartments in Odessa, Ukraine, December 2, 2015. Darth Vader was bent on galactic domination, but his Ukrainian namesake enjoys more mundane pursuits: local politics, walking the family dog and a spot of embroidery. The Ukrainian citizen, who has changed his name to Darth Mykolaiovych Vader, ran for the post of local mayor in October, his political backers dressed as Stormtroopers. In his trademark black outfit, he is a regular sight around Odessa, a major port city on southern Ukraine's Black Sea coast. (Photo by Valentyn Ogirenko/Reuters)

A “Maya” girl sits in an altar during the traditional celebration of “Las Mayas” on the streets in Madrid, Spain Sunday, May 10, 2015. The festivity of the Maya comes from pagan rites and dates from the medieval age, appearing in ancient documents. It takes place every year in the beginning of May and celebrates the beginning of the spring. Girls between 7 and 11 years old are chosen as “Maya” and should sit still, serious and quiet for a couple of hours in altars on the street decorated with flowers and plants and afterwards they walk to the church with their family where they attend a ceremony.
