Art student Marika Cowan says:

A cutout animation project. Music by Kimya Dawson, voice by Cory Hill, poem by Gertrude Stein, sound effects from freesound.org.

The cat puppet and its skull mask is paper painted with acrylics. The tiger is cut out from some tiger-printed patterned paper. All of the backgrounds are paper as well.

This is from the opening piece in Stein’s Tender Buttons (1914), available as an e-book from Project Gutenberg.
