Cursors

You don't need special glasses to view these eye-popping works of 3D street painting, also called anamorphic or illusionistic art. But you will need to approach them from just the right angle to get the full effect.

Cursors meet the classics in this Czech installation by Italian artist Kurt Wenner, who draws with handmade pastels and generally paints between 4 and 6 square yards a day.
