House shoppers in Windermere, Florida can now get detailed real estate listings delivered straight to their cellphones by using text messaging numbers displayed on yard signs. The service is developed by ClearSky Mobile Media and is currently on homes from Main Streat Realtors. That's kinda neat, but to really impress us they'll need to put a WiFi or Bluetooth transmitter on there. And put some LEDs on the sign. And maybe an LCD display, get some moving graphics on there and stuff. Yeah, maybe then.
