Wetness Indicator on Diapers!

Has anyone seen the new Huggies Diapers with wetness indicators?

I bought some Little Snugglers at the superstore last week and when I opened them up and used one, I noticed that there was blue and yellow line running down the middle of the diaper. I realized it told you when the diaper was wet, and thought that it was creativr but silly. Maybe because this is my second child and I know what a soggy diaper looks and feels like, but I found it silly.

Now i just wonder what they will think of next?
