Above Fireplace Ideas Please!

Hi everyone, first time home buyer here with zero interior decorating skills but I'm super excited to move in. I'm a 32 year old bachelor looking for some cool but classy ideas. As you will see, there is an open space above a gas log fireplace which I have no clue what to do with. It is roughly 1 foot deep with an electrical outlet. I was thinking some sort of light display could look cool here. Not interested in a tv going up there as I plan to mount it on the wall or on an entertainment center.

Any and all ideas GREATLY appreciated!
