To be fair a popular thing with some parents is to put a cork or piece of coloured sponge in the toilet to 'train' young boys to 'aim', this is just a high tech version, and if it leads to less public bathrooms looking like men have been standing IN the urinals and pissing out onto the floor, then it has to be a good thing.
I'm only surprised that you're not required to aim at the mouth of a catgirl in school uniform is all, why not go for it, if you're going be distasteful, go hog wild, I think...
