Note: This concept has been beautifully created by a Japanese firm running a campaign on Kickstarter. See it here.
Windoz would be a hang-anywhere window frame with an internal HD flat sreen monitor.
Windoz would display live video streams based on the consumer's selection using the Windoz app.
Live streams could be a gorgeous beach, ski slopes in Vale, the NYC skyline, overlooking the Eiffel Tower in Paris, etc.
