Hello dear Sinister members,
Lately I was thinking alot about enviroment, and how much we are polluting everything around us on daily basis. Awarness among people about this issue is on low level, and yet that's the main reason why we live and breathe here on Earth!
Keeping that in mind, and the fact that I'm planing to start learning programming for android, I would like to hear your ideas for my android application that I will work on. App must be "enviromental", to help people in some kind of indirect way to reduce pollution, greenhouse effect...or just raise, increse awarness among people with some interesting and maybe catchy application?
I know that there are creative people here, who could give me nice ideas, come on!

I would like to hear your opinions. Thank you.
