This app expands on techniques I've used in graphics throughout year one and two graphics modules. I used pixel binning to reduce the webcam footage into a grid of squares, determined on the GUI, which take the first pixel of the bin and colour the square to match that. I then draw the squares using mapped brightness or saturation values to scale to a maximum of the radius from the GUI.
Each box stores the relevant value in a 2D array, so I can access it later. Then, I use an array of 9 random boxes chosen every time the grid is re-initialised, and create a series of sine waves that use the scaling values (brightness/saturation) to alter the frequencies. I add these together using ./25 scaler multipliers to make them sound semi decent/bearable, before using this as the output. The result is a program that reacts to the video in real time, creating sound from video.
