What's material about electronic art?

The computer on which the artist programs/designs/clicks/whatever.
The space which the artist occupies while doing the above.
The artist.
The materials that the artist uses to construct the instantiations of the work.
The gallery in which the art is shown.
If the art is shown on the internet instead of in a gallery, the computers on which the art is viewed.
The wires through which connectivity is conveyed.
The peripherals which are used to interact with the art.
The keyboard, the Wacom tablet, the mouse, the screen, the chair, the desk, the iPad, the cafe, the coffee, the friends and collaborators.
The EU or Canada Council (or whatever) grant, the artist-run centre, the guy who comes in to teach you how MAX works.
The production director who rejects your proposal because the centre doesn't have the necessary resources to execute your project.
