Yep. I have one. It's called a Whiz. It is so cool and they use them in the Armed Forces too. You can also buy a She Wee from any camping store. Doctors say it is better for womens' bladders to stand as we empty better. I take mine if we are travelling.
I love hiking and a friend of mine told me about those. I have tried them out and own one now myself, and they actually work quite well. A nice option when off on a trail and no bathrooms anywhere near us!
I would not use one in a place like in the picture though!
