I was on Amazon a few weeks ago and saw this.
It's called "Flipside" and it's a game/puzzle where you have to line up changing flashing lights. It's fun, it's simple and it's not expensive.
I actually love it! It reminds me of "Bop-It". Remember "Bop-It"?
It's 17 bucks on Amazon. Might be a cool stocking stuffer for the kids or a good, affordable gift for the niece or nephew.
