Saya Woolfalk is a New York–based artist who uses science fiction, technology and fantasy to re-imagine the world and think about how combining cultures can create more utopian societies.

In “Hybrid-Digital Home,” she has collaborated with her six-year-old daughter, Aya Woolfalk Mitchell, to reinvent the ICA’s Art Lab as a warm domestic environment made up of a lively combination of patterns.

The installation combines textile patterns from around the world with computer-generated patterns based on visitor drawings created in Scratch. Developed at MIT, Scratch is a free programming language and online community where children can program and share interactive media.

Visitors of all ages are invited to contribute drawings to be digitally patterned and added to the wall, creating a collaboratively generated portrait of home.

Registration is not required. Families can learn to use Scratch at an ICA family workshop on Aug. 4.
