How Would You Like A Driveway That Twinkled Like Fairy Lights Every Night? http://theownerbuildernetwork.co/h38u It is possible by using "glowstones" in your concrete mix, but it is not cheap. The upside of the extra expense I guess is that you wouldn't need any outdoor lighting as the stones hold light for around 12 hours.
Ooo, low-key lighting for a pathway. This would be nice for a driveway that can be turned on/off and is solar powered. Maybe have a clicker for in your car that toggles the lights, the gate, and the garage?
