Raspberry Pi version

The video synthesizer for Raspberry Pi is a light version of the desktop project. It is considered in Chapter 8, Deploying the Project on iOS, Android, and Raspberry Pi.

This version is the same as the iOS and Android versions described earlier, with a small difference. It doesn't support the double-tap and the accelerometer but reacts to the Esc, Z, Return (Enter), S, and L keys, described in the Control keys section under the The desktop version section.
