Welcome to the Rainbows app, designed by an Xperia SP fan just as a bit of fun, and to share with other Sony Xperia fans.

Firstly, and most importantly, this app requires root access. If your phone is not rooted, then this app will simply do nothing!

Secondly, it was designed to run only on the Sony Xperia SP. Although there are other models that support lighting effects, like the Xperia U, they have a very different way of turning those lights on and off! Again, if your phone is not a Sony Xperia SP, then this app will simply do nothing!

How it works:

The rainbow and dance sequences are based on a bash script originally shared on XDA-Developers forum by nixx-X1 way back in 2013.

Basically, the individual commands from that script are stored here in a database, then called upon in a variety of ways, depending on the chosen effect.
