For some reason unknown to me I find the idea of numbers floating in glass to be particularly entrancing.  I went to some trouble to locate an industrial sample of this large LCD.  Most of the displays I acquire are found in surplus stores, but Liquid Crystal Displays weren't available in surplus when I built this piece.

This is the first piece in which I invested some time making sure that the numbers changed completely at random.  The digits sometimes disappear altogether, then one, 2 or more will pop back into view changing values every second.

I used a circuit that I had designed earlier that creates random numbers based on electrical noise that is sampled to produce randomized bits -- like a digital coin toss.  The upper circular board then turns the random bits into displayable data.
