Film, television, and theatre
In 2015, Classic Alice began a season arc that took its main characters into the woods to recreate Thoreau's classic work.
The National Endowment for the Arts in 2012 bestowed the University of Southern California with a $40,000 grant to create, based on the book, an online video game in which players "will inhabit an open, three-dimensional game world which will simulate the geography and environment of Walden Woods".
Digitization and scholarship efforts
Digital Thoreau, a collaboration among the State University of New York at Geneseo, the Thoreau Society, and the Walden Woods Project, has developed a fluid text edition of Walden across the different versions of the work to help readers trace the evolution of Thoreau's classic work across seven stages of revision from 1846 to 1854. Within any chapter of Walden, readers can compare up to seven manuscript versions with each other, with the Princeton University Press edition, and consult critical notes drawn from Thoreau scholars, including Ronald Clapper's dissertation The Development of Walden: A Genetic Text (1967) and Walter Harding's Walden: An Annotated Edition (1995). Ultimately, the project will provide a space for readers to discuss Thoreau in the margins of his texts.
