Two contemporary art exhibitions worth checking out began earlier this month and will be open through late November at the Centre for Contemporary Art at Ujazdowski Castle in Warsaw.

“Aurorite” is a collection of works by Agnieszka Polska, an artist who uses photography, animation, video and collage to explore the thin line between memory and creation. Ms Polska takes newspapers, books and black-and-white photos as source materials, and uses them to show how the misconceptions that are produced from taking these artifacts out of context can lead to new understandings. Organizers of the exhibition say she is “less interested in what was actually archived, paying more attention to the things that have not been stored.” The works pose the question as to where historical documentation ends and artistic creation begins.

Another exhibition – “Freedom Club” – takes its inspiration from a single set of historical events: the Unabomber case, which unfolded over a period of nearly 20 years in the United States.

The artist, Radek Szlaga, explores the images and ideas that motivated Ted Kaczynski, a former child prodigy, to embark on a campaign of sending deadly bombs in the mail. The mass murderer signed the packages “FC,” which he later said stood for “Freedom Club.” Mr Szlaga’s paintings follow the trail of the Unabomber (and his Polish roots) in an attempt to make sense of this promising mind gone wrong.
