Twins Ryan and Trevor Oakes have developed a drawing technique that captures perspective images on the inside of a sphere.
Their technique involves splitting their vision in two, to trace a scene onto a curved canvass that more accurately captures how it appears in real life.

Using their technique, the twins have produced detailed drawings of the Cloud Gate sculpture ("The Bean") in Chicago, St. Paul's Cathedral in London and the Palazzo Strozzi in Florence, Italy, among others places.
The twins have developed a special apparatus to keep their heads steady while drawing.

To understand their drawing method, hold your hand out in front of your face, then focus on the scene behind it and your hand will go transparent. The twins do the same thing with a curved canvas instead in place of a hand, and trace what they see onto the canvas.

The canvas is curved, Ryan Oakes said, so it can better represent how the human eye bends entering light to produce an image.

Both twins can do the technique, but Trevor Oakes does most of the drawing, while Ryan makes sure everything is set up correctly.

An exhibit of the twins' work, called "Compounding Visions," is on display at Composite: The Gallery at the National Museum of Mathematics.
