Art?

My new installation piece. I think I shall call it "Video tapes buried in bricks and concrete." or do you think that not pretentious enough?

How about "L'homage de canard bleu" ?

Actually - I'm having to re-lay a section of garden railway as the old section had shifted somewhat. The tapes provide both a set of reference levels and something that I can screw the track to eventually - plastic having the advantage (or disadvantage, most of the time) of not rotting.
