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.
