Don't throw out that tea bag!

I love discovering surprising and ingenious ways of reusing something, especially a something that I use a lot. I've just come across this web page that lists various uses for used green tea leaves. My favourite is cat litter deodorizer. Since we use a natural cat litter, Swheatschoop, that doesn't have a deodorizer or perfume and we usually end up buying baking powder just for this purpose. I drink green tea almost every day at work, so I could really amass quite of few leaves. I just need to devise a way of discreetly drying the leaves in my office. :)

What are your favourite ways to use brewed tea leaves?
