ArtWonk 1.5 (Shareware, $199)

ArtWonk is a MIDI and graphics program that produces MIDI music and paint graphics based on algorithmic rules that you interactively create by connecting modules (graphical objects that represent functions and processes) in real time, adjusting the parameters as you go, in an interactive drag and drop environment especially designed to be fast to learn, fast to use. But ArtWonk did not achieve its ease of use by dumbing it down. Quite the contrary. With a starting palette of over 400 built in modules and functions, ArtWonk is one of the most powerful algorithmic composing programs available.

The vOICe Learning Edition 1.62 (Freeware)

The vOICe seeing-with-sound software translates images from a PC camera (webcam) into sounds that you hear via your stereo headphones, thus targetting vision substitution applications for the totally blind, and even synthetic vision. Some blind people wear it daily with a wearable setup to "see" their environment as they go around, while other blind people (blind from birth) use it to experience for the very first time what vision is like. The vOICe uses pitch for height and loudness for brightness in a left to right scan of any view. Apart from using a webcam or equivalent video capture device, images may also be imported from an image file (Control O) or acquired with a flatbed scanner (Control Q).
