Cool Idea: Underwater Disco Light Show

So I stumbled upon this new idea whilst I was doing my Xmas shopping. I thought it was pretty snazy. It's got no real purpose but to look cool and entertain you for a matter of a few minutes. But isn't that what's lifes about?

The website with the product is at:

So what is it?: "A disco ball that floats on the top of a pool, spa or bath that creates an amazing under water light show."
