There Is No Business Like No Business

A blinking neon sign, designed during the recession as a cruel beacon of optimism. The blinking speed is directly proportional to the trading volume of any commodity index chosen by the collector or curator, say NASDAQ or Apple or FTSE100. In a slow day, or when the market is closed, the lines of illuminated text will only switch every 8 seconds, while on the busiest trading day they may blink every 2 seconds. The net effect of the piece is that at a glance of the neon sign one can get a "feel" for how many transactions were done that day.
