Inversion was a 2005 artwork by sculptors Dan Havel and Dean Ruck of Houston Alternative Art.

Havel and Ruck altered two buildings owned by the Art League of Houston on the corner of Montrose Boulevard and Willard Street.

The exterior skins of the houses were peeled off and used to create a large vortex that funneled into the small central hallway connecting the two buildings and eventually exited through a small hole into an adjacent courtyard.

[2] In 2009, the sculptors cut an egg-shaped piece from another house in a work called Give and Take.

[2] In 2011, Havel and Ruck created a work called Fifth Ward Jam, taking planks from the interior of other dilapidated houses in Houston and fixing them to the outside in shapes like an explosion.
