Born in Belgium, artist and architect Francis Alys is known for works that explore simple, ephemeral actions to rather ambitious projects, like when he invited 500 volunteers to collectively move a mountain in Peru. This online exhibit of his work is designed to complement an in situ exhibit at the Museum of Modern Art and MoMA PS 1. Many of the works in the exhibit are drawn from the mid-1990s to the present day, and visitors can view a selection by using the drop-down menus here. The two main areas include still images of some conceptual art pieces, and while they are offered without any specific context, visitors will be able to get a sense of each piece's vision upon close examination of the works. Several of the pieces include video clips, such as "The Modern Procession," which is worth a look.
