While at the Apple store I was blown away by a new room lighting system for a house that creates any color lighting controlled from your phone or tablet. It is expensive, but amazing. The Philips Hue system. Click a sunset, sunrise, rain, etc. The lightbulbs are the same shape, though slightly smaller than the halogen lightbulbs now in our track lighting system. The bulbs change to any color youask. You can simulate a sunset over your specified period of time and the lights change. Each bulb is like a Bluetooth receiver and is mated to a type of router which coordinates the "hue" from all the bulbs together. Starter set $199 for three bulbs and bulbs $60 each. You can activate from anywhere.
I am considering a dozen bulbs or so over the layout.
