OffOn was released on the now out-of-print DVD box set Treasures From American Film Archives, which is fetching high prices on Amazon. Used copies are available for more reasonable prices.
OffOn can also be seen on YouTube.
(A brief clip from OffOn—set to Jimi Hendrix’s “Purple Haze”!—is shown in the documentary Berkeley in the Sixties.)
