In the last quarter of my first year studies I had the choice to create something interactive I like. I had the idea to build interactive balloons. If a person is passing by the flying helium balloons, they light up in different colours with the help of the LEDs I placed inside the balloons. By the end of the quarter I had to pitch my work to my professors. I created the balloons with the help of my advanced processing skills and a good eye for design. 
Here you can see my work, but if you are more interested into that project, just visit my Blog Website for more information!
