The surrealist Pierre Petiot has argued (in "Surrealism and the Machine" (http://my.execpc.com/~bogartte/machine.html)) that the speed the graphical tools of computer periphery permit "allow an almost permanent connection with the roots of automatism". (However, this may be open to criticism on the grounds that mouses, or some individual, makes, or brands of mouses, are not as responsive to the automatic motion of the hand, as are regular drawing implements.)
In 2003Richard Genovese adapted Manchando photographs, the production of which is automatic or automatistic, to the computer.
Automatism is a surrealist technique involving spontaneous writing, drawing, or the like practiced without conscious aesthetic or moral self-censorship.
Automatism in Surrealism has taken a many forms, from the automatic writing and drawing initially practiced by surrealists, to similar, or perhaps parallel phenomena, such and the non-idiomatic improvisation of free jazz [1].
Surrealist automatism is different from mediumistic automatism, from which the term was inspired.
