Wall-mounted spectrum analyzer

Digital art is becoming more and more commonplace, as evident by this wall-mounted specturm analyzer. Since it displays sound from ambient noise, there will never be two similar pieces of “artwork”. Constructed using an array of red LEDs which have been set in a pattern of 8 to 32 bands, this gigantic spectrum analyzer comes with a 4 hours battery life. Alternatively, you can always use AC power for round-the-clok display. The 8-band version already costs a whopping $8,000, so you can (or should I say, can’t) imagine how much the 32-band model costs. It looks pretty simple in nature, so I’m pretty sure the cost is a mere fraction of the retail price. Nevertheless, beauty is in the eye of the beholder, and who am I to stop you if you are adamant on purchasing a piece of art at that price?
