A prototype of a musical interface, driven by cakes.
Essentially, underneath the cakes there is a set of light-dependant resistors (LDRs), and as each cake is moved up and down, readings from the LDRs fluctuate.
These readings are piped from Arduino into Processsing, which then uses the SoundCipher library to play notes. The pitch of the notes is related to the readings from the LDRs.
The cat is all her own work.
