I recently started a new “one-day-project”. It was originally created as a solution for the final peer assessment project on coursera’s “Creative Programming for Digital Media & Mobile Apps“.
Here’s the video that shows the bubble project:
It uses the box2d physics engine to simulate gravity, dependent on the mobile device’s accelerometer’s data. And the code is pretty neat and compact, thanks to some object-oriented concepts..
The submission deadline is 29.07.2013, so I cannot reveal the code right now, but after the submission phase, I will provide a github link for everyone who wants to play and improve the simple bubble melody app.
… And, as promised: https://github.com/zetabeta/one_day_projects/ (BubbleMelody folder)
