Glow-in-the-Dark Countertops

Twice in the past week I've encountered glowing stone surfaces...

And I mean glowing literally, as in back-lit onyx and other natural materials...

First the countertop on an island in the kitchen at a house we looked at in Connecticut.  Not the photo above, obviously that's a bar, but you get the idea.  Then again on a cocktail table at a client's apartment.

I think a bar is the perfect place to apply this trend.  Above is the W Hollywood, looks like a swanky place to grab a cocktail...

I do remember going to the home of a classmate in high school whose mother is an interior designer, and they had back-lit onyx in their powder room, similar to above.  It definitely made a statement, in a good way.  In a home, I think that might be the only place I could handle it.  Or if we had a lounge with a bar.  But in my kitchen?  I'm having a hard time imagining myself baking cookies in a space that looks like James Bond could waltz into at any moment.  The details in the rest of this particular Connecticut home are amazing, down to the Calcutta Gold marble countertops in the rest of the kitchen, so obviously the current homeowners have good taste.  What do you think, am I being a prude, or would a back-lit island just be too much?
