Okay, so that solar-powered electroluminescent wallpaper never caught on, and neither did the EL sports jerseys that stood poised to make the most boring of events at least look exciting. But, this latest application of the tech seems bound to succeed -- if only because it caters to drinking establishments and their affinity for blinking lights. Anokimobi has released a sign that charges during the day, giving it power for up to 14 hours of light pollution at night. It's totally waterproof and can even be powered by an auxiliary power source should a cloudy spell interrupt a week of drunken debauchery. No prices are advertised, but we're sure the company would be happy to send you a quote.
