Mute It
Don't listen to music if you don't want to.
Have you ever crossed some guy that listen to his music at max volume, without headphones, on a public transportation? Then you know how annoying it is. This app scans for the cell phones of people near you, and let you automagically connect to their devices to have full control. The app allows you to stop their music, melt their devices, burn their memory... whatever you want to do...

It's a fictional app, never to be coded (and I guess it would be impossible and illegal to do so), just to train my skills in logo and UI design.
