In the mid 1990s, I made this piece:

It’s made from an old picture tube (removed from the TV for esthetic reasons mostly), with two ghostly babies hovering in space in front of the screen watching it.  The babies have nails driven into their heads to resemble antennas.  While it’s difficult to see in a photo, the lighting and angles are such so that when you look at the screen, you see the reflection of the watching babies, but also your own head complete with antennas coming out the top thanks to the two mounted on the television.  Hopefully it creeps you out a little bit.

This is the first time I made a piece that requires the viewer to be a participant, since without the viewer seeing his own head with antennas, it doesn’t really work.
