Personally I hate GUI's like that, that are dolled up by changing as many properties from their default values as possible.
If I want to achieve something, I simply want the UI to be as standard as possible, and this 'playtime" should be invested in following the HIG to the letter, and setting stuff like tab-order, keyboard shortcuts etc.
Oh, and to the judgemental people, I've made such stresstools many times for perfectly legit purposes.
